Metal transition doping effect on the structural and physical properties of delafossite-type oxide CuCrO2

Résumé

In this paper we reported on the non magnetic substitution effects on the structural, spectroscopic, and magnetic properties of the CuCrO2 delafossite. The incorporation of M3+ generates very anisotropic microstrains in the structure beside a magnetic dilution. The temperature dependence of all samples exhibits paramagnetic behavior at high temperature. It is argued that non magnetic-substitution destabilizes the antiferromagnetic order of Cr3+ ions and modulates the spin configuration leading to a weak ferromagnetism. The coupling between the magnetic order and ferroelectric order is also characterized.
