Abstract
MgO/Cr70Al30/Fe19Ni81 and ZnO/Cr70Al30/Fe19Ni81 layered films with differen t buffer layer thicknesses were prepared on (100)Si substrates in order to investigate the relationship among the exchange-coupling field, the grain s ize, and the lattice constant of the antiferromagnetic layer. The exchange- coupling field was found to consist of the intragrain exchange coupling and the intergrain coupling fields. The former field is inversely proportional to the product of the lattice constant and the grain size. The latter fiel d is constant and changes its sign in association with the increase of the buffer layer thickness. [S0021-8979(98)48311-7] (C) 1998 American Institute of Physics.
