    • 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 ...
