摘要：

The magnetic properties of Yb2BaCuO5 have been examined using Yb-170 Mossbauer spectroscopy down to 0.05 K and magnetic susceptibility measurements down to 1.5 K. The magnetic polarisation of the Yb3+ at each of the two sites is due uniquely to couplings with the Cu2+ moments which are shown to magnetically order at 15 K. The saturated molecular fields at the two Yb3+ sites are 12 and 22 kG and produce saturated Yb3+ magnetic moments of 2.2 and 1.1-mu-B, respectively.
