Query: Mapping the magnetic state as a function of anti-site disorder in Sm$
  _{2} $NiMnO$ _{6} $ double perovskite thin films   The predictability of any characteristic functional aspect in a double
perovskite system has always been compromised by its strong dependence over the
inevitably present anti-site disorders (ASD). Here, we aim to precisely map the
quantitative and qualitative nature of ASD with the corresponding modifications
in observables describing the magnetic and electronic state in epitaxial Sm$
_{2} $NiMnO$ _{6} $ (SNMO) double perovskite thin films. The concentration and
distribution patterns of ASD are effectively controlled by optimizing growth
conditions and estimated on both local and global scales utilizing extended
X-ray absorption fine structure and bulk magnetometry. Depending upon the
defect densities, the nature of disorder distribution can vary from homogeneous
to partially segregated patches. Primarily, the effect of varying B-site
cationic arrangement in SNMO is reflected as the competition of long range
ferromagnetic (FM) and short scale antiferromagnetic (AFM) interactions
originated from ordered Ni-O-Mn and disordered Ni-O-Ni or Mn-O-Mn bonds,
respectively, which leads to systematic shift in magnetic transition
temperature and drastic drop in saturation magnetization. In addition, we have
observed that the gradual increment in density of ASD leads to significant
deviation from uniaxial anisotropy character, reduction in anisotropy energy
and enhancement of moment pinning efficiency. However, the observed signatures
of $ Ni^{2+}+Mn^{4+} \longrightarrow Ni^{3+}+Mn^{3+} $ charge
disproportionation is found to be independent of cation disorder densities.
This work serves as a basic route-map to tune the characteristic magnetic
anisotropy, magnetic phase transitions, and magnetization reversal mechanism by
controlling ASD in a general double perovskite system.
