  "abstract": "The effect of thermal surface cleaning on the Gilbert damping, $\\alpha$, of yttrium iron garnet (YIG), before capping with a metallic layer, has been investigated. Our results show that $\\alpha$ is strongly effected by relatively mild annealing conditions (T = 300 C) when performed in a vacuum. This increase needs to be taken into account when obtaining the spin mixing conductance from spin pumping measurements. We measure an increase in $\\alpha$ by a factor of 8 when the YIG is vacuum annealed at 300 C. No such changes in $\\alpha$ are observed when annealed at the same temperature in 0.1 mbar of oxygen.",
