Abstract

The surface morphology, crystal structure and exchange bias of CrO ₂ particles were investigated. The epitaxial relationship of Cr ₂ O ₃ layers on CrO ₂ particles was investigated using electron diffraction, high-resolution electron microscopy (HRTEM) and fast Fourier transform (FFT). The exchange bias of the annealed CrO ₂ particles was observed using random field model. The selected area electron diffraction (SAED) patterns were observed for the annealed particles indicating good crystallinity.
