Abstract

Using ac susceptibility, dc magnetization and heat capacity measurements, we have investigated the magnetic properties of $C d_{0.5} C u_{0.5} C r_{2} O_{4}$ . $C d_{0.5} C u_{0.5} C r_{2} O_{4}$ has an extraordinary magnetic phase including a metastable spin-glass(SG) phase at zero field, a possible phase separation scenario of AFM/FM above $\sim 0.5 T$ field, and at intermediate fields, an apparent pseudo reentrant spin-glass (RSG) plateau is observed. These phenomena are closely correlated with the pinning effect of the $C u^{2 +}$ sublattice on the frustrated lattice.
