Abstract

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 (Tp) which is observed for all the PSMO nanometric samples, differs from the ferromagnetic to paramagnetic transition temperature (Tc) 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.
