Abstract
We report, for the first time, temperature dependent pole-reversal of magnetization for La1-xCexCrO3 (x = 0.8, 1.0) nanoparticles. The Rietveld refinement of the x-ray diffraction patterns confirmed the single phase nature of the samples (Orthorhombic: Pbnm). From the transmission electron microscopy (TEM) image, the average particle size is found to be ∼44 nm. High resolution TEM reveals surface defects/roughness which corroborates a core-shell nature. The magnetic properties of these nanoparticles have been tuned by Ce3+ substitution. The novel pole-reversal phenomenon has been explained using the core-shell model, and can be exploited to fabricate advanced magnetic memory devices.
