Query: Termination-dependent Electronic and Magnetic Properties of Ultrathin
  SrRuO$_{3}$ (111) Film on SrTiO$_{3}$   We have investigated electronic and magnetic properties of ultrathin
SrRuO$_{3}$ (SRO) film grown on (111) SrTiO$_{3}$ substrate using the {\it ab
initio} electronic structure calculations. Ru-terminated SRO (111) film suffers
from strong surface atomic relaxations, while SrO$_{3}$-terminated one
preserves the surface structure of ideal perovskites. Both Ru- and
SrO$_{3}$-terminated SRO (111) film show unexpected interlayer
antiferromagnetic (AFM) structure at the surface, but with different characters
and mechanisms. The AFM structure for the former results from the large surface
atomic relaxation, whereas that for the latter results from the truncated film
effect. Interestingly, for the SrO$_{3}$-termination case, the half-metallic
nature emerges despite the interlayer AFM structure. Upon reducing the
thickness, the collapsing behavior of magnetic anisotropy from out-of-plane to
in-plane easy axis is found to occur for the Ru-termination case, which,
however, does not pertain to SrO$_{3}$-termination case.
