  SSMO5347 thin films (thicknesses ~200 nm) were deposited by on-axis dc
magnetron sputtering on the single crystal LSAT (001) substrates. These films
are oriented along the out of plane c-direction. The ferromagnetic and
insulator-metal transition occurs at 96 K and 91 K, respectively. The
magnetization easy axis is observed to lie in the plane of the film while the
magnetic hard axis is found to be along the normal to this. The
magnetotransport of the SSMO films, which was measured as a function of angle
(theta) between the magnetic field (H) and plane of the film, shows colossal
anisotropy. Magnetoresistance (MR) decreases drastically as theta increases
from 0 degree (H//easy axis) to 90 degree (H//hard axis). The out-of-plane
anisotropic MR (AMR) is as high as 88 % at H=3.6 kOe and 78 K. The colossal
anisotropy has been explained in terms of the magnetic anisotropies at play and
the magnetic domain motion in applied magnetic field.
