Abstract

The surface morphology, crystal structure and exchange bias of CrO 2 particles were investigated. The epitaxial relationship of Cr 2O3 layers on CrO2 particles was investigated using electron diffraction, high-resolution electron microscopy (HRTEM) and fast Fourier transform (FFT). The exchange bias of the annealed CrO2 particles was observed using random field model. The selected area electron diffraction (SAED) patterns were observed for the annealed particles indicating good crystallinity.
