Magnetic Thin Film Characterization
An improvement on the fabrication of magnetic thin films is currently on a level of intense research as these films are of great interest in the device industry. Some of these thin films posses high permeability and ferromagnetic resonance (FMR) frequency in the GHz range which are suitable for electromagnetic use. Methods for fabricating these films include sputtering, pulse laser deposition (...

متن کاملCoercivity of permanent magnetic thin film.
The coercivity of magnetic thin film having a two-dimensional easy-axis distribution is investigated within the framework of a simple micromagnetic model. It is found that the coercivity decreases from 0.14H(K) to a minimum of 0.07H(K) as thickness increases, where H(K) is the anisotropy field. It is substantially lower than that given by the Stoner-Wohlfarth model and is consistent with availa...
متن کاملInterlaboratory Comparison of Magnetic Thin Film Measurements
A potential low magnetic moment standard reference material (SRM) was studied in an interlaboratory comparison. The mean and the standard deviation of the saturation moment m s, the remanent moment m r, and the intrinsic coercivity H c of nine samples were extracted from hysteresis-loop measurements. Samples were measured by thirteen laboratories using inductive-field loopers, vibrating-sample ...
