The CPPGMR element of the present invention has an orientation layer 12 formed on a substrate 11 to texture a Heusler alloy into a (100) direction, an underlying layer 13 that is an electrode for magneto-resistance measurement stacked on the orientation layer 12, a lower ferromagnetic layer 14 and an upper ferromagnetic layer 16 each stacked on the underlying layer 13 and made of a Heusler alloy, a spacer layer 15 sandwiched between the lower ferromagnetic layers 14 and the upper ferromagnetic layers 16, and a cap layer 17 stacked on the upper ferromagnetic layer 16 for surface-protection. This manner makes it possible to provide, inexpensively, an element using a current-perpendicular-to-plane giant magneto-resistance effect (CPPGMR) of a thin film having a trilayered structure of a ferromagnetic metal/a nonmagnetic metal/a ferromagnetic metal, thereby showing excellent performances.

By using silicon oxynitride with an oxygen content of 4.2 to 37.5 at % as a material for a barrier layer, adhesiveness similar to that of silicon oxide and an Ag diffusion prevention property similar to that of silicon nitride can be realized. In particular, in a semiconductor device in which a plurality of silicon chips is vertically stacked by through-silicon vias, Ag is prevented from being diffused into Si and adhesiveness to Si becomes favorable when an Ag/polypyrrole complex is used as a conductive filling material used for the formation of a barrier layer provided on the inner surface of the via.

The development of lithium-ion batteries has energized studies of solid-state batteries, because the non-flammability of their solid electrolytes offers a fundamental solution to safety concerns. Since poor ionic conduction in solid electrolytes is a major drawback in solid-state batteries, such studies have been focused on the enhancement of ionic conductivity. The studies have identified some high performance solid electrolytes; however, some disadvantages have remained hidden until their use in batteries. This paper reviews the development of solid electrolytes and their application to solid-state lithium batteries. © 2012 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
