Abstract
We have fabricated an oxide thermal rectifier made of La 1:98Nd 0:02CuO 4 and MnV 2O 4. By utilizing a jump of a thermal conductivity originated in the structural phase transition accompanied by the orbital ordering in MnV 2O 4, a rectifying coefficient of 1.14 has been achieved in the presence of a small temperature difference of 2 K. A thermal rectifier operating under a small temperature difference will play an important role for realizing heatcurrent control in electronic devices.
