摘要：
Grain size effect on electronic-and magnto-transport properties of hole doped manganite Pr0.7Sr0.3MnO3 (PSMO) in nanometric dimension has been thoroughly investigated under external magnetic field range from zero to +/- 8 Tesla down to 4 K. Metal-insulator transition temperature (T-P) which is observed for all the PSMO nanometric samples, differs from the ferromagnetic to paramagnetic transition temperature (T-C) in the nanometric regime compare to its reported bulk counterpart mainly due to the enhanced surface disorder effect. Temperature dependent low field complex magneto-impedance (LFMI) behaviour has also been studied in presence of external magnetic field range of 0 - 800 Oe down to 77 K.
