    Dry Etching of MRAM Structures

    A wide variety of GMR and CMR materials have been patterned by high density plasma etching in both corrosive (Cl2-based) and non-corrosive (CO/NH3) plasma chemistries. The former produce much higher etch rates bu...

    Plasma chemistries for dry etching of NiFe and NiFeCo

    Plasma chemistries based on chlorine, bromine, or iodine have been investigated for inductively coupled plasma etching of NiFe and NiFeCo. There is clear evidence of a chemically enhanced etch mechanism with b...

    Dry and Wet Etch Processes for NiMnSb, LaCaMnO3 and Related Materials

    A variety of plasma etching chemistries were examined for patterning NiMnSb Heusler thin films and associated A12O3 barrier layers. Chemistries based on SF6 and Cl2 were all found to provide faster etch rates tha...

    Structural and Magnetotransport Properties of NiMnSb/Cu and NiMnSb/Ag Multilayers

    We report on the integration of the predicted half-metallic (100% spin-polarized) ferromagnetic Heusler alloy NiMnSb into NiMnSb/Cu and NiMnSb/Ag multilayer structures, and on their magnetic, microstructural a...

    Low-Temperature Growth of NiMnSb Heusler Alloy Thin Films

    Ferromagnetic Heusler alloys such as NiMnSb may have unique applications to magnetoresistive devices because of their predicted half-metallic band-structure (i.e., 100% spin-polarized at the Fermi level). Howe...

    Sputter-deposition of NiMnSb magnetic thin films from a composite target onto Si substrates

    We have deposited ferromagnetic NiMnSb thin films by sputtering from a single composite target onto Si wafer substrates. Similarly to earlier results using glass substrates, we find that a combination of low r...

    Process-Induced Uniaxial Magnetic Anisotropy in Epitaxial Fe and Ni80Fe20 Films

    The occurrence of a weak in-plane uniaxial magnetic anisotropy in Fe thin films grown by molecular beam epitaxy onto (001)-oriented MgO substrates has been previously reported. We explain the occurrence of thi...
