Abstract
The magnetic susceptibility of a powder sample of RbFeF3 has been measured from 12° to 300°K in magnetic fields up to 11 kOe. Its Curie constant agrees with S=2 and g=2.17 for an Fe2+ ion. Its Néel point is 75°K. The data yield the exchange interactions for a two‐sublattice model: W12=−43.9°K, W11=+4.5°K, and W22=−7.5°K. The ratios of θ to TN (1.17) and of W11 to W12 (0.10) are consistent with a magnetic ordering of the first kind. Weak ferromagnetism occurs around 74°K. The weak ferromagnetic moment extrapolates to about 0.27 μB (Bohr magnetons) at 0°K and corresponds to a canting angle of 1°56′.This publication has 5 references indexed in Scilit:
