Query: Robust perpendicular magnetic anisotropy in Ce substituted yttrium iron
  garnet epitaxial thin films   Cerium substituted yttrium iron garnet (Ce:YIG) epitaxial thin films are
prepared on gadolinium gallium garnet (GGG) substrate with pulsed laser
deposition (PLD). It is observed that the films grown on GGG(111) substrate
exhibit perpendicular magnetic anisotropy (PMA) as compared to films grown on
GGG(100) substrate. The developed PMA is confirmed from magneto-optical Kerr
effect, bulk magnetization and ferromagnetic resonance measurements. Further,
the magnetic bubble domains are observed in the films exhibiting PMA. The
observations are explained in terms of the growth direction of Ce:YIG films and
the interplay of various magnetic anisotropy terms. The observed PMA is found
to be tunable with thickness of the film and a remarkable temperature stability
of the PMA is observed in all the studied films of Ce:YIG deposited on GGG(111)
substrate.
