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 ...

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 ...
