摘要：

Complementary specific heat data on "green phase" R2BaCuO5 (R=Y,Sm,Eu,Gd,Dy,Ho,Er,Tm,Yb,Lu) compounds and Zn-based Gd2BaZnO5 and Y2BaZnO5 are obtained. Details of phase transition in Dy2BaCuO5, specific heat upturn in the Yb2BaCuO5, dimensionality of magnetic interactions in the Y2BaCuO5 and Lu2BaCuO5, the role of Cu2+-O2--R3+-O2--Cu2+ chains in magnetic exchange are discussed.
