Abstract

The effect of the insertion of nonmagnetic Cr planes on coercivities of thin Co films has been studied in Co/Cr multilayered films. The in-plane coercivity H_c∥ can be as high as 1800 Oe and can be adjusted easily, ranging from 650 to 1800 Oe. The large H_c∥ is related to the Co(110) in-plane orientation which is induced by a Cr(100) in-plane-oriented underlayer. In addition, it appears that a decreasing saturation magnetization M_s, a decreasing average structural coherence length D in the direction perpendicular to the film, and a narrowing distribution of D are correlated to the increasing in H_c∥. The effects of texture, Cr interlayers, D and its distribution, and the Cr underlayer on the magnetic properties are discussed.
