Abstract
ESR experiments on powder samples of SrCuO 2 and Sr 2 CuO 3 have been tried in the submillimeter wave region. No resonance absorption has been observed on freshly prepared samples at the temperatures from 86 K to 265 K, while the samples left in the air for a few months have revealed distinct magnetic resonance signals around g =2. Especially the complicated line shape of Sr 2 CuO 3 suggests the overlap of two kinds of EPR, one of which is related to the EPR observed in SrCuO 2 . From the results of H 2 O gas exposed samples, the effect of H 2 O to these samples is discussed.Keywords
