previously reported that the compensation temperature of DyIG is Tcomp = 225 K [2,3], which could decrease the Faraday rotation angle of Dy:CeIG in this work at the temperature below 300 K. Therefore, a higher Faraday rotation may be related to the increase of the saturation magnetization of this material in this temperature range. Revisions:Page 5, line 170-173, added “The increase of the Faraday rotation below 40 ℃ is possibly due to the increase of the magnetization of this material at this temperature range, considering a compensation temperature of 225 K in Dy3Fe5O12 [19,20].”.

This manuscript relates to the effect of dysprosium substitution in Ce:YIG thin films and in particular to the temperature dependance of their Faraday rotation.
