Submillimeter wave ESR measurements of R2Cu2O5 (R=Y, Lu, Sc and In) powder samples have been performed for the frequency range from 90 to 380 GHz and for the temperature range from 1.8 to 265K using the pulsed magnetic field up to 16T. The g-values and the line width are obtained from the results of EPR absorption. Below TN, the changes of the' ESR modes have been observed at the magnetic fields corresponding to the metamagnetic transitions observed in the magnetization measurements.
