抜粋

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.
