JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS(2001)
摘要
The crystallographic and magnetic properties of YBa2Cu3-xRhxOy and YBa2CU3-xIrxOy (x = 1,2,3) have been studied. The structures are orthorhombic, tetragonal and cubic with a mixture of them. YBa2Ir3Oy is a weak ferromagnet with T-C = 185 K. YBa2Cu2RhOy and YBa2CU2IrOy are antiferromagnetic with T-N = 14 K. The other compounds are paramagnetic. (C) 2001 Elsevier Science B.V.
