Thermal transport in CuCr2X4 (X=S,Se,Te): Experiment and ab initio calculations
Original language description
We present a combined experimental and theoretical study of the longitudinal and transverse thermoelectric properties of ferrimagnetic spinels CuCr2X4 (X = S, Se, Te). The thermoelectric power of all studied phases is positive and consists of two contributions, an almost linear diffusive thermopower observed at high temperature,and a strong enhancement below TC attributed to magnon drag. The diffusive part of thermopower and resistivity decreases from X = S to Te, whereas the magnon drag enhancement is the biggest for X = Se, which has also the highest TC. The thermopower was calculated by DFT method using GGA, GGA + U, GGA+oeeHyb, and mBJ potentials. A good agreement with the experimental thermopower was achieved using GGA potential for X = S and with mBJ potential for X = Te. T
