    Studies of deposition order anomaly of exchange coupling in bilayers and trilayers of NiFe and CoO 

    Ambrose, T.; Leifer, K.; Hemker, K. J.; Chien, C. L. (American Institute of Physics, 1997-04-15)
    The temperature dependence of the exchange field and coercivity and the effect of deposition order have been studied in a series of bilayer (NiFe/CoO and CoO/NiFe) and trilayer (NiFe/CoO/NiFe) films. A profound difference ...

    Exchange coupling between Cr and ferromagnetic thin films 

    Yang, F.Y.; Chien, C.-L. (American Institute of Physics, 2003-05-15)
    Exchange bias has been observed in Ni81Fe19/Cr bilayers. The exchange bias field for Cr thickness tCr larger than 62 Å increases with tCr and levels off at tCr=150 Å, whereas coercivity increases without saturation. The ...

    Memory effects of exchange coupling in CoO/Ni81Fe19 bilayers 

    Gokemeijer, N.J.; Chien, C.-L. (American Institute of Physics, 1999-04-15)
    By changing the field-cooling procedure, the value and even the sign of the exchange field HE in CoO/Ni81Fe19 bilayers can be greatly altered. The value of HE can be made to vanish at any temperature below TN. We also show ...

    Long-range exchange coupling between a ferromagnet and an antiferromagnet across a nonmagnetic spacer layer 

    Gokemeijer, N.J.; Ambrose, T.; Chien, C.-L.; Wang, N.; Fung, K.K. (American Institute of Physics, 1997-04-15)
    The antiferromagnet/ferromagnet exchange coupling giving rise to a shifted hysteresis loop has usually been considered an interfacial effect. We show evidence that this exchange coupling between an antiferromagnet (CoO) ...

    Dependence of exchange coupling on antiferromagnetic layer thickness in NiFe/CoO bilayers 

    Ambrose, T.; Chien, C.-L. (American Institute of Physics, 1998-06-01)
    A systematic study of the dependence of exchange coupling in NiFe/CoO bilayers on CoO layer thickness tAF from 5 to 500 Å has been made. For large CoO thicknesses (tAF>100 Å), the exchange field varies as 1/tAF, whereas ...

    Doubly exchange-biased NiCoO/NiFe/Cu/NiFe/NiCoO spin valves 

    Ambrose, T.; Liu, K.; Chien, C.-L. (American Institute of Physics, 1999-04-15)
    A new type of doubly exchange-biased Ni50Co50O/NiFe/Cu/NiFe/Ni30Co70O spin-valve structure, with two ferromagnetic layers exchange biased in opposite directions by two different antiferromagnetic layers is demonstrated. ...

    Longitudinal and perpendicular exchange bias in FeMn/(FeNi/FeMn)n multilayers 

    Sun, L.; Zhou, S.M.; Searson, P.C.; Chien, C.-L. (American Institute of Physics, 2003-05-15)
    Exchange bias in ferromagnetic (FM)/antiferromagnetic (AF) bilayers is usually investigated in the longitudinal configuration with the exchange coupling established in the film plane. In this work, we report on the ...

    Exploiting finite size effects in a novel core/shell microstructure 

    Liu, Zhu; Xia, Guoqiang; Zhu, Frank; Kim, Su; Markovic, Nina; Chien, Chia-Ling; Searson, Peter C. (American Institute of Physics, 2008-03-15)
    Electrodeposition of Ni-Cu alloys at high Cu(II) concentration and large overpotentials results in phase separation with a unique microstructure characterized by features with a copper-rich core and a nickel-rich shell. ...
