Structural, Raman Spectroscopy, and Magnetic Ordering in New Delafossite-Type Oxide CuCr1−x Ti x O2 (0≤x≤0.1)

We investigated in this paper a new mixture +3/+2 B cations delafossites by the doping at Cr3+ sites in CuCrO2 by nonmagnetic cation Ti2+. Ceramics of CuCr1-x Ti x O2 (0-Ox-O0.1) were prepared via solid state synthesis techniques in a controlled atmosphere of O2. The compound crystallized into the 3...

Summary:We investigated in this paper a new mixture +3/+2 B cations delafossites by the doping at Cr3+ sites in CuCrO2 by nonmagnetic cation Ti2+. Ceramics of CuCr1-x Ti x O2 (0-Ox-O0.1) were prepared via solid state synthesis techniques in a controlled atmosphere of O2. The compound crystallized into the 3R delafossite phase with hexagonal structure. The slightly different size in B cations induced a slightly variation in unit cell parameters. We modulate the spin chirality by the effect of spin dilution for Ti2+ on the structural and magnetic properties of delafossite CuCrO2 having a S=3/2 antiferromagnetic triangular lattice (ATL).
