Abstract

We have investigated substitution effects on transport, magnetic, and thermal properties of delafossite CuCrO2 having a spin-3/2 antiferromagnetic triangular sublattice by measurements of resistivity, magnetization, specific heat, and neutron scattering. In the proceeding, we show unique effects of hole-doping by a substitution of nonmagnetic Mg2+ ions for magnetic Cr3+ ions (S = 3/2), randomness introduced between CrO2 layers by a substitution of Ag+ ions for Cu + ions, and spin-defect introduced into CrO2 layers by a substitution of nonmagnetic Al3+ ions for Cr3+ ions upon the magnetic state in CuCrO2.
