abstract = {We report and quantify a large orbital-Hall torque
generated by Nb and Ru, which we identify from the strong
dependence of torques on the ferromagnets. This is
manifested as strong enhancement in the dampinglike torques
measured in Nb (or Ru)/Ni bilayers as compared to Nb (or
Ru)/FeCoB bilayers including the sign reversal in the case
of Nb/(Ni or FeCoB) samples. We experimentally observe a
striking enhancement of the measured torques with the
increase of ferromagnetic Ni thickness which is markedly
different from the regular spin-transfer torque; this could
be a unique signature of long-range action of the
orbital-Hall torques.},
