Abstract

We prepared SrCuO2 thin film by radio-frequency magnetron sputtering on glass substrate and have investigated its postannealing effects on structure and thermal conductivity. The as-sputtered film belongs to two-dimensional spin system SrCuO2, namely, layer-type SrCuO2, which has a possibility of exhibiting high, anisotropic thermal conductivity by magnetic excitation of the spins. It was found that the as-sputtered film has (001)-orientation in which the spin layers are parallel to the surface of substrate and that post-annealing results in enhancement of crystallinity of the film such as disappearance of grain boundaries, which can cause an increase in thermal conductivity.
