Abstract
Magnetic measurements and Mössbauer effect (ME) studies of 57Fe in CsFeF3 are reported. The compound is hexagonal at room temperature, but undergoes a crystallographic transformation at 83°K to a structure with lower symmetry. Magnetization data show a spontaneous magnetization appearing at TC=62°K, with a saturation magnetization at low temperatures of 1.72 μB per formula unit. In the magnetic state ME yields well resolved hfs corresponding to the two magnetically inequivalent iron sites. At 4.2°K the following hyperfine structure parameters have been obtained: Heff(A)=318 kOe, Heff(B)=274 kOe; Q.S. (A)=−2.85 mm/sec, and Q.S. (B)=−1.9 mm/sec, with the axes of the EFG tensors at 40° to the direction of the magnetic moments.This publication has 8 references indexed in Scilit:
