Magnetic properties of Co-M-C (M=Zr, Hf, Ta) films

Influence of heat treatment on the structure and magnetic properties of the Co/Zr and Co/Hf multilayer amorphous films

“…For instance, compounds with higher Co concentration should be formed at the initial stages and with higher Zr concentration in the final stages (3,5). Enhanced thermal stability, as the Zr or Hf concentrations in amorphous multilayer films increase, could be connected to the slowing of diffusion and the rise in the nucleation energy for the crystalline phase.…”

“…Their great promise for use in thin film heads for high-density magnetic recording has been reported in several papers [4,5].…”
