英文摘要srxla2-xcu0.5ru0.5o4 (x = 1, 1.5) oxides with k2nif4-type structure were prepared by solid state reaction and characterized by powder x-ray diffraction, x-ray photoelectron spectroscopy, magnetic and electrical resistivity measurements. the srlacu0.5ru0.5o4 phase was obtained for the first time with a negligible amount of impurities. the octahedral cu/ruo6 units are more elongated in srlacu0.5ru0.5o4 than in sr1.5la0.5cu0.5ru0.5o4 indicating a greater extent of static jahn-teller distortion. xps suggests that mixed ion pairs ru5+/ru4+ <-> cu+/cu2+ are present in srlacu0.5ru0.5o4, while ru remains as rus and cu as cu2+ in sr1.5la0.5cu0.5ru0.5o4. both samples show spin-glass behavior, which can be explained by competition between ferromagnetic and antiferromagnetic superexchange interactions. the negative weiss temperature estimated for srlacu0.5ru0.5o4, -318 k, is significantly lower than -11.5 k deduced for sr1.5la0.5cu0.5ru0.5o4 which may be related to the higher static jahn-teller distortion in the former oxide.
