摘要：

Magnetic susceptibility and specific heat measurements are presented for some Cu-containing phosphates with different copper frameworks, M2Cu(PO4)(2) (M = Sr and Ba: linear 1D uniform chains), BaCuP2O7 (double 1D uniform chains), MCuP2O7 (M = Ca, Sr, and Pb: zig-zag 1D uniform chains), and Sr9.1Cu1.4(PO4)(7) (isolated Cu2+ ions). We observed short- and long-range magnetic ordering in these compounds in which the main Cu-Cu interactions are transferred through PO4 groups. In M2Cu(PO4)(2) and BaCuP2O7, J/k(B) values of about 100-140 K and k(B) TN/J< 1% were obtained. (C) 2004 Elsevier B.V. All rights reserved.
