摘要：

The intrinsic coercivity of the SmCo based permanent magnetic films prepared on the hot Si substrate at 650℃ with Al, Cu, Ag, Mo, and Cr underlayer without a subsequent annealing process was investigated. The results show that the films with Mo and Cr underlayer provide an improved intrinsic coercivity. The film thickness presents a complex effect on the intrinsic coercivity of the films with Mo underlayer. When the film thickness is 3.0 µm, the maximum value of the intrinsic coercivity is 281.6 kA·m-1 at room temperature. Furthermore, the temperature dependence of intrinsic coercivity is found to be strongly correlated with the magnetic parameters. In the range from 25℃ to 300℃, the intrinsic coercivity of the films of above 200 kA·m-1 is obtained. Copyright © 2015, Northwest Institute for Nonferrous Metal Research. Published by Elsevier BV.
