In this study, we show the temperature dependence of magnon spin diffusion length in a magnetic insulator. The magnon spin diffusion length is determined by using a non-local magnon transport measurement geometry, which is consist of two Pt stripes for magnons injection and detection. We observe rapid increase of the magnon spin diffusion length below 100K.
