Title: SPIN VALVE ELEMENT
Abstract:
A spin valve element (10) which has: a spin injector (12) comprising a ferromagnetic body; a spin detector (16) comprising a ferromagnetic body; and a channel (14) comprising a non-magnetic body. The spin detector (16) is disposed at a position separate from the spin injector (12), the channel part (14) is connected to the spin injector (12) and the spin detector (16) either directly or via an insulating layer, and spin diffusion parts (30-34) having an enlarged cross-sectional area in the direction orthogonal to the spin current are formed in the channel part (14).
