The critical angle of the spin-flop transition (3.1° at T = 0) is determined in the rhombic antiferromagnet (C2H5NH3)2CuC14 (TN = 10.2 K), and its temperature dependence in the interval 1.7−10 K is studied. It is established that ψcr decreases monotonically as the temperature increases. A new procedure is proposed for determining the critical angle.
