    Soft-magnetic properties of Fe–Co–B thin films for ultra-high-frequency applications (2000)

    Notes: Fe67Co18B15 amorphous thin films were sputter deposited on glass substrates under a uniform applied magnetic field. The films exhibit excellent soft-magnetic properties of 4πMs∼17.5 kG, Hc∼0.3 Oe, and Hk (anisotropy field) ∼22 Oe. The ultra-high-frequency performance on these films was studied and the relative permeability μ′ is shown to be as high as ∼740 and almost constant to at least 1 GHz. The combination of high 4πMs and relatively high Hk in these films is believed to be partly responsible for the excellent ultra-high-frequency behavior. The soft-magnetic properties of these films show a strong dependence on the film deposition bias voltage, which presumably changes the microstructure of the films and the related magnetic anisotropy. © 2000 American Institute of Physics.

    Modulation-induced giant magnetoresistance in a spinodally decomposed Cu-Ni-Fe alloy : 38th Annual Conference on Magnetism and Magnetic Materials (1994)

    Notes: Giant magnetoresistance in a spinodally decomposed, bulk 60 Cu-20 Ni-20 Fe alloy is reported. An annealed, quenched, and heat-treated sample with a compositional modulation of (approximately-less-than)50 A(ring) size exhibits a ΔR/R value as high as 9% at 4.2 K. Optimization of the ferromagnetic phase particle geometry through a combination of spinodal decomposition and uniaxial deformation led to a locally multilayered, superlattice-like structure and a dramatic increase in room-temperature magnetoresistance from ∼0.6 to ∼5%. This improvement in magnetoresistance is accompanied by a decrease in coercivity from ∼620 Oe in the fully decomposed material to ∼45 Oe in the optimized structure. Interestingly, this structure no longer exhibits the commonly observed temperature-dependent behavior of ΔR/R increasing at low temperatures, but rather shows a decrease at 4.2 K.

    Giant magnetoresistance in spinodally decomposed Cu–Ni–Fe films : The 6th joint magnetism and magnetic materials (MMM)−intermag conferenc (1994)

    Notes: We report the observation of the GMR effect in spinodally decomposed Cu–20Ni–20Fe thin films. A ΔR/R value as high as 6.5% was observed at room temperature. In contrast to the commonly observed temperature-dependent behavior of ΔR/R increasing at low temperature; thin film shows a decrease in ΔR/R at 4.2 K. The dependence of the GMR effect on various deposition parameters, such as substrate temperature has been studied. The observed giant magnetoresistance behavior in Cu–20Ni–20Fe films is most likely related to the field-induced decrease in electron scattering in a pseudosuperparamagnetic material, as well as the spin-dependent scattering at the two-phase interface and in the ferromagnetic phase.

    Giant magnetoresistance in melt-spun Cu80Ni10Fe10 ribbons : The 40th annual conference on magnetism and magnetic materials (1996)

    Notes: Magnetoresistance (MR) behavior in melt-spun ribbons of a Cu80Ni10Fe10 alloy has been studied. The rapid solidified ribbon, when properly heat treated for phase decomposition, exhibits giant magnetoresistance behavior with the MR values of 8.5% at room temperature and 29% at 4.2 K. The observed magnetoresistance in the alloy is attributed to spin-dependent scattering at the two-phase interface and in the ferromagnetic phase. The substantial increase in MR, as the temperature decreases from room temperature to 4.2 K, is most likely caused by the reduction of spin-flip scattering of conducting electrons in the paramagnetic regions as a result of magnetic transformation. © 1996 American Institute of Physics.

    Low-field magnetostriction in an annealed Co–30% Fe alloy (1999)

    Notes: Magnetostriction properties of a deformed and annealed Co–Fe alloy have been investigated. A significant magnetostriction value greater than ∼110×10−6 was obtained in a cold-rolled and recrystallized sample at a practical, low field of ∼100 Oe, while the as-cold-rolled sample gave a small magnetostriction of only ∼15×10−6 for the same applied field. Cold rolling and recrystallization produces much smaller magnetostriction in the longitudinal direction than the transverse direction in the low-field regime. The saturation magnetostriction of the recrystallized Co–Fe alloy was ∼140×10−6. The drastic dependence of the magnetostriction behavior on the alloy processing is tentatively attributed to the microstructure and texture changes brought about by the heat-treatment processing. The availability of such a high magnetostriction in low applied fields using a ductile and low-cost alloy material can be useful for various technical applications. © 1999 American Institute of Physics.

    Theoretical investigation on quantum well lasers with extremely low vertical beam divergence and low threshold current (1998)

    Notes: A specially designed quantum well laser for achieving extremely low vertical beam divergence was reported and theoretically investigated. The laser structure was characterized by two low index layers inserted between the waveguide layers and the cladding layers. The additional layers were intended to achieve wide optical spread in the cladding layers and strong confinement in the active region. This enabled significant reduction of beam divergence with no sacrifice in threshold current density. The numerical results showed that lasers with extremely low vertical beam divergence from 20° down to 11° and threshold current density of less than 131 A/cm2 can be easily achieved by optimization of the structure parameters. Influences of individual key structure parameters on beam divergence and threshold current density are analyzed. Attention is also paid to the minimum cladding layer thicknesses needed to maintain low threshold current densities and low internal loss. The near and far field patterns are given and discussed. © 1998 American Institute of Physics.

    Ultrahigh frequency permeability of sputtered Fe–Co–B thin films (2000)

    Notes: Amorphous FeCoB alloys can have high resistivity and relatively high saturation magnetization which are desired for ultrahigh frequency devices such as future write heads and wireless inductors. In this study, FeCoB films are observed to have a low easy axis coercivity (1–2 Oe), a field deposited induced anisotropy of ∼35 Oe and 4πMs∼17 500 G when sputtered in a typical configuration. However, samples sputtered in an off axis arrangement are found to have an additional uniaxial anisotropy as a result of the oblique incidence of the atomic flux onto the substrate. This extra anisotropy increases with increasing oblique angle. For these same samples, there is little change in the easy axis coercivity, saturation magnetization, and the Hoffmann structure factor (S∼0.05 ergs/cm2). The obtained large anisotropy fields (〉35 Oe) are found to push the ferromagnetic resonance frequency to at least above 1 GHz at the expense of the initial permeability. © 2000 American Institute of Physics.
