Hk. Sohn et al., EFFECTS OF P-ADDITION ON MAGNETIC-INTERACTIONS AND MICROSTRUCTURES INCO-CR-P-PT MAGNETIC THIN-FILMS, IEEE transactions on magnetics, 31(6), 1995, pp. 2803-2805
We have studied the effects of P addition in. a new alloy system of Co
-Cr-P-Pt with the coercivity higher than 2600 Oe even when they were d
eposited without substrate heating and bias voltage. The addition of P
increased the Co{1010} texture and decreased the Co{0002} texture, wh
ich is one of the reasons for the higher in-plane coercivity. The magn
etization reversal mechanism changed from domain wall motion to curlin
g type incoherent rotation with the addition of P. As the P content in
creases, delta M gradually shifts from positive to negative. This can
be associated with enhancement of grain isolation and the reduction of
out-of-plane orientation with the addition of P.
