Herein we have investigated the effect of Cu(3d − transition metal) substitution for the Ir – site on the structure and physical properties of Sr2IrO4. Interestingly, the critical octahedral rotation is found to decrease (increase in Ir – O – Ir angle) with Cu substitution. The resistivity measurements illustrate a significant decrease with Cu substitution, however, keep a semiconducting dependence. Magnetic measurements reveal a decrease in the magnetic transition temperatures. Observed magnetic moment per metal ion shows a decreasing trend as Cu content is increased in the structure. A study of the composition – structure – properties correlation for this interesting and mixed 3d − 5d transition metal system is presented and discussed here.< Réduire
