Abstract
Paramagnetic and antiferromagnetic resonance have been observed in single crystals of Bi 2 CuO 4 in submillimeter wave region using pulsed magnetic fields at temperatures from 4.2 K to 265 K. At the paramagnetic state, g -values have been determined to be g // =2.26±0.01 and g ⊥ =2.04±0.01. The angular independent line-widths are 0.37±0.03 T which is quantitatively explained by the dipole interaction and anisotropic exchange interaction. An antiferromagnetic resonance mode of planer type antiferromagnet has been observed below the Néel temperature and explained by the conventional antiferromagnetic theory.Keywords
