摘要

Exchange coupling effect has been studied in the as-deposited (1 1 1), twinned (1 1 0) and (2 1 1) oriented CoMn/Ni80Fe20 films grown on Mo or Pt seeding layer by molecular beam epitaxy. Uniaxial magnetic anisotropy was observed in all cases mainly due to the epitaxial strain between the Ni80Fe20 and seeding layers. We observed that the exchange bias field (coercivity) is relatively large (small) for the (1 1 1) oriented CoMn/Ni80Fe20 film compared to those of the twinned (1 1 0) and (2 1 1) samples. The orientational dependence of the exchange coupling effect in the as-deposited CoMn/Ni80Fe20 film is very similar to that of the FeMn/Ni80Fe20, where uncompensate plane seems not required for significant exchange bias effect, in marked contrast to the case of PtMn/Ni80Fe20.
