Abstract:The isothermal magnetization of a NdAl2 single crystal has been measured at 4.2 K, along the main symmetry directions in static fields up to 150 kG. In this ferromagnetically ordered compound, [100] is the easy direction of magnetization and [111] the hard direction. Taking into account the tetragonal distortion observed along the [100] direction an effective crystal field Hamiltonian is derived and values are obtained for the crystal field parameters of second, fourth, and sixth order. The effects of the dist… Show more
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.
