Using a vector network analyzer, temperature dependence of spin wave transmission is measured. We observe a clear resonance frequency shift of 210 MHz with temperature change of 40 K. This can be explained by the dispersion variation of the temperature. These results enable a complete pass or forbidden spin wave propagation in a certain frequency window with temperature control which might lead to application of spin wave filters.
