Query: Enhancing the blocking temperature of perpendicular-exchange biased
  Cr2O3 thin films using spacer and buffer layers   In this study, we investigated the effect of spacer and buffer layers on the
blocking temperature TB of the perpendicular exchange bias of thin Cr2O3 films,
and revealed a high TB of 260 K for 20-nm-thick Cr2O3 thin films. By inserting
a Ru spacer layer between the Cr2O3 and Co films and changing the spacer
thickness, we controlled the magnitude of the exchange bias and TB. By
comparing the TB values of the 20-nm-thick Cr2O3 films on Pt and alpha-Fe2O3
buffers, we investigated the lattice strain effect on the TB. We show that
higher TB value can be obtained using an alpha-Fe2O3 buffer, which is likely
because of the lattice-strain-induced increase of Cr2O3 magnetic anisotropy.
