Query: Spin Peltier effect and its length scale in Pt/YIG system at high
  temperatures   The temperature and yttrium-iron-garnet (YIG) thickness dependences of the
spin Peltier effect (SPE) have been investigated using a Pt/YIG junction system
at temperatures ranging from room temperature to the Curie temperature of YIG
by the lock-in thermography method. By analyzing the YIG thickness dependence
using an exponential decay model, the characteristic length of SPE in YIG is
estimated to be 0.9 $\mu$m near room temperature and almost constant even near
the Curie temperature. The high-temperature behavior of SPE is clearly
different from that of the spin Seebeck effect, providing a clue for
microscopically understanding the reciprocal relation between them.
