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.
