Abstract :
The magnetic anisotropy of Co100-xCr14Pt8Bx longitudinal thin film recording media sputtered onto Al/NiP substrates is determined as a function of boron concentration (x = 4at% to x = 16at%) using high field (~4.5T) ferromagnetic resonance (FMR) and the Miyajima technique. The variation of coercivity with field exposure time is also measured over two different time regimes allowing the median reversal field, in the absence of thermal activation, H0.
