摘要：

Specific heat, ac magnetic susceptibility and magnetization in static and in pulse fields were measured for polycrystalline "green phase" R2BaCuO5 (R = Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb) samples. Two magnetic phase transitions were found in these compounds at temperatures T(N1) and T(N2). An assumption is made that the antiferromagnetic ordering of copper and rare earth subsystem occurs at T(N1) and T(N2), respectively. The Dy, Ho and Er compounds have been shown to be metamagnetic at temperatures below T(N2).
