Title:
SPIN CONDUCTIVE DEVICE
Document Type and Number:
Japanese Patent JP2010238956
Kind Code:
A
Abstract:

To provide a spin conductive device having improved characteristics by suppressing diffusion of metal atoms of magnetized free layers, magnetized fixed layers, and tunnel insulating layers to channel layers.

The spin conductive device 100 includes a channel layer, a metal oxide layer 8 that is provided on the channel layer and includes one of an aluminum oxide, a titanium oxide, a zinc oxide, and a beryllium oxide, a magnesium oxide layer 9 provided on the metal oxide layer 8, a magnetized free layer 12C provided at a first part of the magnesium oxide layer 9, and a magnetized fixed layer 12B provided on a second part of the magnesium oxide layer 9.
