    Magnetic particle–particle interaction in frozen magnetic fluids (1996)

    Notes: Magnetic resonance is used to study magnetic dipole particle–particle interaction in ionic water-based iron-manganese magnetic fluids. A set of six samples having particle concentration running from 1.2×1016 to 6.3×1016 particles/cm3 were frozen below room temperature and analyzed in the range of 100–250 K. Average values of magnetic particle–particle interaction energy were obtained from the temperature dependence of the resonance linewidth broadening. At 1.2×1016 particles/cm3 magnetic particle–particle interaction energy is found to be of the order of 1.2 meV. However, at 6.3×1016 particles/cm3 magnetic particle–particle interaction energy goes to 32 meV. The enhancement of the magnetic particle–particle interaction energy far beyond the linearity is associated to cluster structuration. A one-dimensional model for cluster structuration is presented. © 1996 American Institute of Physics.

    Influence of intense laser field on the tunneling current in semiconductors (1985)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 58 (1985), S. 4473-4476

    Topics: Physics
    Notes: The influence of an intense laser field on the quasienergy gap of a semiconducting crystal as developed in the presence of an exciting laser field is discussed. It is shown that the effect of the strong laser is of "dressing'' the quasienergy gap in that it becomes modulated by the strong field amplitude. The consequence of this latter effect on the tunneling current between a semiconductor-semiconductor junction is discussed. An application is made for a GaAs sample.

    Microvibration sample magnetometer: A force-type measurement (1985)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 56 (1985), S. 411-414

    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: A simple microvibrating sample magnetometer (MVSM), particularly inexpensive, sensitive, and versatile has been developed. An alternating magnetic field superposed to a steady uniform magnetic field is applied to the sample. The sample undergoes a periodic motion around an equilibrium position, causing a pressure fluctuation within a closed gas cell which is detected as an acoustic signal by a microphone.

    Temperature dependence of the Mössbauer linewidth of superparamagnetic particles of ferric hydroxysulfate (1985)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 57 (1985), S. 1291-1293

    Topics: Physics
    Notes: The Mössbauer linewidth broadening of superparamagnetic particles of ferric hydroxysulfate, near the point where the paramagnetic lines begin to appear, has been investigated as a function of temperature. This behavior is explained by a geometric picture of an assembly of magnetically ordered single-domain particles whose magnetic moments move within an asymmetric double-well potential. A relaxation model is presented which combines the conventional theory of superparamagnetism with an exponential distribution of energy barriers.
