| dc.description | Simultaneous studies on the magnetic and electrotransport properties of Nd_{0.67} Sr_{0.33} Mn_{1-x} Fe_x O_3 polycrystalline bulk and epitaxial thin films (x = 0.00 and 0.05) have been carried out. A magnetoresistance (MR) as high as ~ 33% is observed for Nd_{0.67} Sr_{0.33} MnO_3 bulk at the metal-insulator transition (MIT) temperature (T_p) of 273 K in a magnetic field (H) of 10 kOe. Fe substitution at Mn sites reduces the ferromagnetic (FM) ordering temperature (T_c) and leads to an overall increase in MR. MR as high as ~ 90% is observed for thin film (x = 0.05) at H = 10 kOe with T_p = 100 K while the corresponding bulk has a MR of only ~ 43%. Low field MR in epitaxial thin films also display a pronounced anisotropy effect compared to bulk materials. | |
