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 > Tc = 30 K and the nearly isotropic g-value 1.92 was obtained. The anisotropic FMR observed below Tc for YTiO3. On the other hand, very weak EPR was observed at around g = 2 for LaTiO3 at T > TN = 140 K, but we were not able to observe antiferromagnetic resonance below TN for LaTiO3.
