We have prepared a trial oxide thermal rectifier made of two cobalt oxides with different thermal conductivities based on a theoretical design. We created an experimental system to measure the thermal rectification and found that the rectifying coefficient defined by the ratio of heat current in a forward direction to that in the opposite direction was 1.43. We verified the thermal rectification by analyzing it quantitatively.
