Correlation of Co[110]/Cr[002] texture and magnetic properties in CoCrTaPt granular films

Abstract

Studies of the effects of substrate temperature T, on the evolution of CO( 1 10)/Cr(002) texture, magnetic and physical grain size, intergrain-interaction, anisotropy, orientation ratio of remanence and coercivity were investigated experimentally. It is found that the hcp-Co(l10)hcc-Cr(002) texture is improved with increasing T, from 27OC to 265°C. The intergrain-interaction, magnetic and physical grain size decrease with increasing Ts and reach their minima at T,-265°C where the magnetic grain size is close to the physical grain size. The correlation between the film microstructure and magnetic properties is studied systematically.Index tems--Co( 1 lO)/Cr(OO2) texture, magnetic grain, intergraininteraction, x-ray rocking curve.

Effect of crystalline disorder on magnetic switching in small magnetic cells

“…A lot of work in material science has been done over many years to examine how magnetic parameters are influenced by the composition and micro structure of thin films [1][2][3][4][5][6][7][8][9] .Models of disordered ferromagnets were studied analytically by Ignatchenko and co-workers in the late 1970s and early 1980s (see 10 and references therein) as well as by Kronmüller and coworkers 12 . They derived "laws of approach of the magnetization to saturation".…”
