摘要Cr0.68Se single crystals with two-dimensional (2D) character have been grown, and the detailed magnetization M(T), electrical transport properties (including longitudinal resistivity rho(xx) and Hall resistivity rho(xy)), and thermal transport properties [including heat capacity C-p(T) and thermoelectric power S(T)] have been measured. There are some interesting phenomena: (i) Cr0.68Se presents a non-collinear antiferromagnetic (AFM) semiconducting behavior at the Neel temperature of T-N = 42 K and with the activated energy of E-g = 3.9 meV; (ii) it exhibits the anomalous Hall effect (AHE) below T-N and large negative magnetoresistance about 83.7% (2 K, 8.5 T). The AHE coefficient R-S is 0.385 cm(-3)/C at T = 2K, and the AHE conductivity sigma(H) is about 1 Omega(-1) cm(-1) at T = 40 K; (iii) the scaling behavior between the anomalous Hall resistivity rho(A)(xy) and the longitudinal resistivity rho(xx) is linear, and further analysis implies that the origin of the AHE in Cr0.68Se is dominated by the skew-scattering mechanism. Our results may be helpful for exploring the potential application of these kinds of 2D AFM semiconductors. Published by AIP Publishing.
