Angular dependence of magnetization reversal in epitaxial CHROMIUM TELLURIDE (cas 12053-39-3) thin films with perpendicular magnetic anisotropy

Add time:07/27/2019    Source:sciencedirect.com

We investigate magnetic anisotropy and magnetization reversal mechanism in CHROMIUM TELLURIDE (cas 12053-39-3) thin films grown by molecular beam epitaxy. We report existence of strong perpendicular magnetic anisotropy in these thin films, along with a relatively strong second order anisotropy contribution. The angular variation of the switching field observed from the magnetoresistance measurement is explained quantitatively using a one-dimensional defect model. The model reveals the relative roles of nucleation and pinning in the magnetization reversal, depending on the applied field orientation. Micromagnetic simulations are performed to visualize the domain structure and switching process.
