Inhomogeneous spin glass and mixed phases in cerium compounds
Source abstract
Abstract
Abstract We discuss the properties of the spin glass phase observed in the CeNi 1− x Cu x system. We have measured the AC susceptibility, field cooled and zero field cooled magnetization, hysteresis loops, magnetic relaxation and neutron scattering. An inhomogeneous magnetic arrangement, namely spin glass-like state, is proposed. A description consisting of nanometric magnetic clusters embedded in a non-magnetic matrix is likely for the richer Ni compounds. We support this hypothesis as a consequence of the coexistence of chemical disorder in the Ni/Cu crystallographic sites, the random and coherent anisotropy, the competing magnetic interactions and large 4f-conduction band hybridization.
