Abstract
The exchange biasing field (H-eb) and coercive field (H-c) of molecula r-beam-epitaxy (MBE) grown Cu/Ni80Fe20/Fe50Mn50 samples in [111], [001 ] and [110] orientations were investigated by Kerr effect measurements . A strong dependence of H,, and H, on the growth orientation is obser ved. A strong uniaxial in-plane anisotropy introduced by the Fe50Mn50 layer was found for the [110]-oriented sample. Conversion electron Mos sbauer studies revealed a roughness of 2-3 A and no significant moment reduction at the Ni80Fe20/Fe50Mn50 interface.
