Antiferromagnetic magnetization dynamics is more effective than ferromagnetic magnetization; however, it is extremely complex. Rare earth (RE) ferrimagnets, on the other hand, have tunable magnetization with associated negative exchange interaction in sublattices. Here, we study different RE-Fe ferrimagnets while changing the RE-content. We obtain various magnetic properties like saturation magnetization MS, coercivity HC, magnetic anisotropy energy constant Ku, exchange coupling constant λ, and compensation temperature Tcomp for different RE compositions. We suggest that along with MS and HC, λ is another important parameter that is easy to measure and has information that is similar to that in the spin-orbit torque effective field and the canting angle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
