Temperature dependences of the ESR spectrum in Y/sub 2/Cu/sub 2/O/sub 5/ compound are studied for both polycrystalline and single crystal samples. The g-factors along the main axes are found to be g/sub a/ = 2.099, g/sub b/ = 2.048, and g/sub c/ = 2.21 at room temperature, T = 293 K. As temperature decreases, the linewidth /Delta/H increases in agreement with the Huber's formula /Delta/H = A(T/sub N//(T - T/sub N/))/sup /beta// + B(/theta//T + 1) with the following parameters: A = 1513 +- 10 Oe, B = 509 +- 10 Oe, T/sub N/ = 7 +- 1 K, /theta/ = 18 +- 2 K, /beta/ = 1.3 +- 0.3. In the vicinity of the Neel Temperature, T/sub N/, the ESR spectrum has a very complicated form indicating the existence of clusters with different internal magnetic fields. Below T/sub N/, a single line symmetrical ESR spectrum is recovered.
