Abstract

Submillimeter wave ESR of stoichiometric powder samples of Mott-Hubbard insulator RTiO₃ (R = Y, La) has been performed in the frequency region from 50 to 300 GHz. The EPR was observed for YTiO₃ at T > T_c = 30 K and the nearly isotropic g-value 1.92 was obtained. The anisotropic FMR observed below T_c for YTiO₃. On the other hand, very weak EPR was observed at around g = 2 for LaTiO₃ at T > T_N = 140 K, but we were not able to observe antiferromagnetic resonance below T_N for LaTiO₃.
