Role of Surface on Magnetic Properties of La1-xSrxMnO $_{3+\delta }$ Nanocrystallites

Abstract

The magnetic La1-xSrxMnO3 particles of ≈50 nm size have been prepared in the flux of sodium nitrite at ≈500°C. A detailed magnetic study, including the neutron diffraction at zero and high pressures, has been performed on compositions x = 0.28 and 0.37, as well as on comparative samples prepared via sol-gel route. Based on these experiments, we conclude… (More)
