Abstract

Cyclotron resonance (CR) and magnetic resonance measurements on single crystals of GdSb have been performed at temperatures between 1.4 K and 30 K in the frequency range from 50 to 110 GHz. By using a high-quality crystal with the residual resistivity ratio of about 500, two CR absorption lines are observed at low temperatures for B ∥ [001] in addition to an antiferromagnetic resonance. The effective mass values are estimated to be 0.26m0 and 0.50m0, respectively, which are reasonably consistent with the results of dHvA measurements. On the other hand, in the case of a low grade crystal, a magnetic resonance of Gd impurities is observed. The absorption line of the impurities shows broadening and g-shift at low temperatures.
