Query: Asymmetric Pt/Co/Pt structure as a platform for extracting pure spin
  Hall torque   We have quantitatively studied the spin-orbit torque purely generated by the
spin Hall effect in a wide range of temperatures by intensionally eliminating
the Rashba spin-orbit torque using Pt/Co/Pt trilayers with asymmetric
thicknesses of the top and bottom Pt layers. The vanishingly small contribution
from the Rashba effect has been confirmed through the vector measurements of
the current-induced effective fields. In order to precisely determine the value
of the spin Hall torque, the complete cancelation of the spin Hall torque has
been verified by fabricating symmetric Pt/Co/Pt structure on SiO2 and Gd3Ga5O12
(GGG) substrates. Despite of the complete cance- lation on the GGG substrate,
the spin Hall torque cannot be completely canceled out even when the top and
bottom Pt layers have same thicknesses on the SiO2 substrate, which suggests
that Pt/Co/Pt trilayers on a GGG substrate is a suitable system for precise
measurements of the spin Hall torque. The result of the vector measurements on
Pt/Co/Pt/GGG from 300 to 10 K shows that the spin Hall torque is almost
independent of temperature, which is quantitatively reproduced under the
assumption of the temperature-independent spin Hall angle of Pt.
