ABSTRACT
An unusual diamagnetic response is observed in a Pr60Al10Ni10Cu16Fe4 bulk metallic glass (BMG) during the zero-field-cooled (ZFC) magnetization measurement. The ZFC magnetization of the BMG is found to reverse its direction at low temperature and becomes diamagnetic, whereas the field-cooled branch remains positive. This apparent diamagnetism is ascribed to the specific couple between the ferromagnetic nanoparticles and the amorphous matrix in low fields. Besides, in superconductors, a giant diamagnetic response is unusual in magnetic materials. Therefore, it may simulate scientific and technological interest.

    We investigate the magnetoresistance (MR) of spin valves by (i) varying the strength of the field applied in a fixed direction and (ii) rotating the field with fixed strength. The latter data reflect in general a mixture of giant and anisotropic magnetoresistance (GMR and AMR). We present an...

    In superconductor/ferromagnet hybrids, the stray field and inhomogeneous exchange field coming from magnetic domain walls have opposite influence on the superconductivity if the ferromagnet displays in-plane anisotropy. In this paper, we investigate modulation of superconductivity by the stray...
