ABSTRACT
We developed a spin valve with oxide specular layers that shows a giant magnetoresistance value of 20%. The spin valve also showed an exchange bias field of over 1000 Oe. The giant magnetoresistance was mainly due to an increase in the sheet resistance change and resulted from additional specular reflection at the interface of the free layer. The method we used was to modify specularly reflective oxide layers of the free and the capping layers.

    The enhancement of the ordinary magnetoresistance (OMR) in Si has been attempted by constructing two type of Co/Si systems; one is the sputter-deposited current perpendicular to plane-type Co/Si multilayers and the other is the sputtered-Co/anodized-porous-Si system. The Co/Si multilayers show...

    The orthorhombic SrIrO3 perovskite was synthesized under 5 GPa and 1000 °C. It is paramagnetic below about 170 K and transfers to an unknown magnetism under higher temperature. A band type metal to insulator transition caused by a pseudogap was observed at about 44 K. Interestingly a positive...
