摘要：
yThe structural, transport and magnetic properties of RuSr2Sm1.4Ce0.6Cu2O10-delta have been studied. The increase of oxygen content results in a decrease of lattice parameters and an increase of superconducting transition temperature. For Raman spectra, the hardening of the 650 cm(-1) mode with decreasing temperature is due to the thermal contraction of lattice. Magnetic measurements exhibited a ferromagnetic transition around 150 K, indicating the coexistence of superconductivity and ferromagnetism in this compound. (C) 2003 Elsevier B.V.
