The magnetic properties of CaxZn1−Fe2O4 (with x in the range 0.0–1.0) were investigated using Mossbauer spectroscopy and a.c. susceptibility measurements. X-ray diffraction patterns and Mossbauer data suggest that this system exists as single-phase spinel when x 0/8. When samples are sintered in air, the Neel temperature of Ca0.5Zn0.5Fe2O4 is 27 K. When samples are sintered in flowing oxygen the Neel temperaturesof ZnFe2O4 and Ca0.5Zn0.5Fe2O4 increase to 150 K and 205 K respectively. The room… CONTINUE READING
