摘要：

Antiferromagnetic resonances (AFMR) and EPR of R(2)Cu(2)O(5) (R=Y, Lu, In) powders have been observed from 1.8 K to 265 K by submillimeter wave ESR in the frequency region 90 to 383 GHz using pulsed magnetic field up to 16 T. The frequency field relations below T-N turned out to be quite different among above materials. AFMR modes have been analyzed by the model which was used previously to interpret the two successive metamagnetic transitions observed in the magnetization process of R(2)Cu(2)O(5).
