A non-volatile memory element that is called a perpendicular- anisotropy magnetic tunnel junction has been fabricated in a CoFeB/MgO/CoFeB film stack technology. It exhibits two stable resistance values, high or low, depending on the relative dire...

The valence states of the Mn ions in Pr(1-x)A(x)MnO(3-delta) (A = Ca, Sr) are investigated by Mn-L-3 X-ray absorption near-edge structure (XANES) analysis. The spectral fine structures in the Mn-L-3 XANES analysis show a significant difference bet...

The memory reliability of magnetic tunnel junctions has been examined from the aspect of their potential use in disaster-resilient computing. This computing technology requires memories that can keep stored information intact even in power-cut eme...
This paper presents analysis results for the onorbit performance of a solar array paddle of the X-ray astronomy satellite Suzaku. The current generated by the solar array was decreasing significantly for approximate one year after mid-2011. We est...
