摘要：

ESR experiments on powder samples of SrCuO2 and Sr2CuO3 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 Sr2CuO3 suggests the overlap of two kinds of EPR, one of which is related to the EPR observed in SrCuO2. From the results of H2O gas exposed samples, the effect of H2O to these samples is discussed.
