摘要

Low-temperature high-magnetic-field far-infrared spectroscopy and electron-spin-resonance measurements have been performed on single crystals of the cubic perovskite (Formula presented) We found the absorption at (Formula presented) observed by Richards [P. L. Richards, J. Appl. Phys. 34, 1237 (1963)] that was attributed to antiferromagnetic resonance (AFMR) is not magnetic in origin. Instead, a different absorption is well fit by a theory of AFMR with uniaxial anisotropy. Analysis yields an anisotropy energy of (Formula presented) The ratio between the anisotropy field and the exchange field is (Formula presented) Thus, (Formula presented) is an excellent example of a Heisenberg antiferromagnet.
