Abstract

THE presence of antiferromagnetic ordering in LaCrO3 has been verified before by both neutron diffraction1 and static magnetic susceptibility2 techniques. In the former case, a Neel temperature of approximately 320° K. is reported, while the susceptibility results indicate Tn ≍ 295° K. Above Tn, LaCrO3 is paramagnetic and hence amenable to investigation by standard electron paramagnetic resonance techniques. We have carried out the experimental resonance investigations over the temperature-range 200–450° K.
