Abstract
Nanodimensional silica based glass containing iron ions was prepared within the compressed pellet of CuO nanoparicles. The nanocomposite material showed exchange bias effect. This effect arose due to ferromagnetic iron doped CuO phase and antiferromagnetic CuO interface formation within the nanocomposite during the synthesis process. Coercive field as a function of temperature was fitted with Arhenius-Neel equation and extracted blocking temperature was 511Â K. The value of effective anisotropy constant for the nanocomposite was found to be 3.64x105Â erg/cc.
