    Thermoelectric phenomena in metals under large temperature gradients (1991)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 69 (1991), S. 3375-3377

    ISSN: 1089-7550

    Topics: Physics
    Notes: Nonlinear contributions to thermoelectricity are studied when large temperature gradients are present in metals. A theory is presented to account for these phenomena in the case of monovalent metals obeying a parabolic dispersion law. Simple experiments are proposed in which nonlinear terms are relevant and produce measurable effects.

    Laser-plasma generation of currents along a conductive target (1990)

    Notes: Large electric currents have been observed along conductive targets on which plasma was initiated by means of spatially modulated radiation. Two successive pulses of TEA CO2laser with intensities I≤109 W/cm2 were used in the experiments. The most effective generation of the currents was observed during the second laser pulse delayed for 4 μs, when an asymmetric plasma "grating'' was produced on the target. Two different mechanisms for generating such currents in a closed circuit have been established. One of them results from a dipole moment of plasma, while the other is due to the processes at plasma-surface interface. To obtain correct measurements of the voltage induced by a laser plasma, a fiber optical modulator of light has been used for the first time.

    Silicon-based surface plasmon resonance combined with surface-enhanced Raman scattering for chemical sensing (1997)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 68 (1997), S. 2554-2557

    Notes: A Si-based surface plasmon resonance (SPR) technique has been successfully applied to NO2 sensing at ppm level, with estimated detectability at less than 100 ppb. Surface-enhanced Raman scattering (SERS) has been used in this scheme as an inherent additional data acquisition channel capable of providing spectroscopic selectivity and amplified sensitivity. The behavior of both the SERS spectrum and the SPR-induced photosignal produced by Au-on-Si grating structures coated with thin 18-crown-6 metal-free phthalocyanine films was simultaneously recorded for exposure of the films to 10 ppm of NO2 in air and its reversal in clean air. Both responses have been found to be reversible. The combination of Si-based SPR and SERS looks promising for thin-film and surface explorations, both in fundamental and sensor applications. © 1997 American Institute of Physics.

    Experimental observation of magnetostochastic resonance : The 6th joint magnetism and magnetic materials (MMM)−intermag conferenc (1994)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 76 (1994), S. 6335-6337

    Notes: We report an observation of magnetostochastic resonance (MSR) in bistable magnetic systems. MSR manifests itself as a peak of a response of such a system to a periodic field as a function of the noise strength. Bi-substituted ferrite-garnet films with uniaxial anisotropy were used as simple examples of bistable systems. Noise was produced by (i) thermal fluctuations of an effective magnetic field and (ii) externally applied "noiselike'' magnetic fields. The position of the peak depended dramatically on the magnitude of applied dc fields, so that dc fields of about 1 mOe in the spatial scale of 10 μm were measured. MSR applications to various tunneling phenomena such as tunneling of magnetization in small magnetic particles are discussed.

    Frequency mixing phenomena in a bistable system : The 40th annual conference on magnetism and magnetic materials (1996)

    Notes: A response of a bistable system subject to several periodic and random forcing is discussed. It is shown that spectrum components of the response on mixed frequencies demonstrate a noise-induced enhancement typical for stochastic resonance. The quenching of the spectrum harmonics due to an application of a constant force that destroys symmetry of the potential is calculated. The theory is checked on a simple bistable magnetic system: a local part of a domain wall in a thin ferrit–garnet film. © 1996 American Institute of Physics.

    Experimental study of spontaneous electric field generated by a laser plasma (1998)

    Notes: We report investigations of a space-time structure of the electric field of laser plasma from a solid target. An ArF excimer laser with an intensity of I≅108 W/cm2 was used to produce the plasma on various targets placed in air at atmospheric pressure. A strong difference in both the amplitude (by more than 1–2 orders of magnitude) and the structure of the electric field for conductive and dielectric targets has been observed. The field distribution for a conductive target was found to correspond to a dipole configuration of charges in the laser plasma, while for the dielectric target a quadrupole configuration was revealed. Possible explanations and applications of the observed effect are discussed. © 1998 American Institute of Physics.

    Amorphous magnetic films produced by pulsed laser deposition (1997)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: Amorphous magnetic Fe–Co–Ni–Si–B films have been produced on silicon and glass substrates by means of XeCl excimer laser ablation of amorphous magnetic ribbons. Laser fluence, the number of pulses, and target–substrate distance were the variable parameters. The films were studied with x-ray specular reflectivity, x-ray diffraction, x-ray photoelectron spectroscopy, profilometry, and ellipsometry. Laser ablation has been found to provide a good transfer of composition and structure from the ribbon targets to the deposited films, with excellent mechanical and optical quality of the films. Magnetic properties of the films were examined by a technique based on the magneto-optical Kerr effect. The films revealed well-defined in-plane uniaxial anisotropy. They demonstrated coercivity and anisotropy field values comparable to those of the initial ribbons, and much higher steepness of substantially rectangular hysteresis loops. The films can have a number of prospective applications in magnetic sensors, switches, and concentrators. © 1997 American Institute of Physics.

    New method of magnetic field and current generation outside laser plasma (1996)

    Topics: Physics
    Notes: A new mechanism of laser plasma generation of current along an irradiated conductive target, and a considerable (more than 1000 times) enhancement of magnetic field outside the plasma has been found. This mechanism is realized in experimental configurations with spatial asymmetries of target dimension scale. Such asymmetries with the largest possible scale was found to be the main factor that determines electromagnetic phenomena detected by external probes outside the laser plasma. © 1996 American Institute of Physics.

    Evidence of ferromagnetic behavior of small liquid droplets produced from amorphous alloys by laser ablation (1998)

    Notes: Experimental evidence of ferromagnetic behavior of liquid droplets produced by laser ablation from amorphous alloys is presented. Thin films of amorphous magnetic materials were fabricated by laser ablation deposition in the presence and in the absence of a magnetic field. The difference in parameters of deposited films is attributed to ferromagnetic properties of small size liquid droplets. © 1998 American Institute of Physics.
