Description

The low temperature crystallographic and magnetic phase transitions in the mixed crystal system Dysub(p)Gdsub(1-p)VO4 (0<=p<=1) have been studied using thermal expansion measurements and Moessbauer spectroscopy. The introduction of magnetic Gd3+ ions into the DyVO4 host causes an anomalous dip in the Neel temperature Tsub(N)(p), and a rapid reduction of the distortion temperature Tsub(D)(p) which differs from results on similar mixed systems. A number of pseudo-spin Hamiltonians that model these observations are discussed. (author)
