We have performed millimeter wave ESR. measurements of (DMET) 2FcBr4 single crystals, which consist of electric quasi ID chain-based donor layers and magnetic Fe3+ square lattices, in the temperature region from 1.8 K to 70 K. We observed the splitting of absorption line at 130 GHz, and the estimate the exchange interaction between d-electrons and π-electrons. The temperature dependence of ESR at low temperature is discussed in connection with the conventional antiferromagnetic resonance (AFMR).
