Abstract

Multiferroic CuCrO2 ceramics doped with Sn4+ ions were fabricated by solid state reaction. XRD and Raman results indicate that the Sn4+ doping results in the lattice expansion without causing any damage to the delafossite structure of CuCrO2. The cell volume of CuCr1-xSnxO2 increases form 130.86 Å3 for x = 0 to 131.19 Å3 for x = 0.05, while the grain size decreases with the increase in Sn4+ doping content. XPS analysis reveals that the Sn element is in the + 4 state, and it does not change the valence state of the Cr (+3) element in CuCrO2. Magnetic properties measurements suggest that all the samples exhibit nearly the same magnetic transition temperature at about 26 K, however, the low temperature magnetic order is changed from a coexistence of ferromagnetic and antiferromagnetic phases in CuCr1-xSnxO2 (x = 0 and 0.01) to a single antiferromagnetic phase in CuCr1-xSnxO2 (x ≥ 0.02) samples.
