  We investigate the magnetic and magnetotransport properties of nanostructured
Nd0.6Sr0.4MnO3 (NSMO) thin films grown on (100) oriented SrTiO3 (STO)
substrates. The thin films fabricated using the pulsed laser deposition
technique have been found to possess two distinct surface morphologies:
granular and nano rod type. Magnetization measurements have revealed that the
films with rod-type morphology exhibit improved in-plane magnetic anisotropy.
Magnetotransport studies have revealed that the granular thin films display a
characteristic butterfly-shaped low-field magneto-resistive (LFMR) behavior.
Furthermore, we investigate the anisotropic magneto-resistive (AMR) phenomenon
in the samples and we find that morphology greatly affects AMR. Thin films with
rod-type morphology show an enhanced AMR %. Such morphology dependent
tunability in magnetoresistance properties over a wide temperature range is
potentially interesting for developing oxide-based sensors and devices.
