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).
Scope of claims [claim1]

(Claims machine translated from Chinese)
[claim2]
1. Kinds of spinning valve parts, have: Pours into part by spinning that the ferromagnetic substance is constituted;
Picks out part by spinning that the ferromagnetic substance is constituted;
And by channel department that the non-magnetic body is constituted, above spinning picks out the part is the disposition is injecting the position that with above spinning the part separates, the above channel department is direct or pours into the part and above spinning above spinning by way of the insulating layer connection picks out the part, forms to split the area in the above channel department toward with from the spinning proliferation department that the direction of eddy quardrature expands.
[claim3]
2. Like request item of 1 spinning valve part, the above spinning proliferation department is forms is, pours into the part to face above spinning to pick out 1st of from above spinning the direction parts spinning of resistance way to pick out the part to face above spinning from above spinning to inject 2nd the direction part spinning of resistance way to be also smaller.
[claim4]
3. Like request item 1 or 2 spinning valve part, the above spinning proliferation department has above splits the area to become the biggest former nose, pours into the part side to face the situation of above nose with the nose before above to face above spinning before above spinning to pick out the situation of part side to compare, above spinning proliferation department with above from the direction of eddy quardrature splits the area rate of change department to be small.
[claim5]
4. Like request item 1 to threes any item of spinning valve part, above spinning pours into the part and above spinning to pick out the part and above channel department is forms on the foundation plate, above spinning pours into the part and above spinning picks out the part is being parallel the direction to separate the disposition with foundation plate's main surface mutually.
[claim6]
5. Like request item of 4 spinning valve parts, by the above view it of above foundation plate, the above spinning proliferation department is takes through above splits the area biggest former nose and with above the line that extends from the direction of eddy quardrature forms asymmetrically for the datum.
[claim7]
6. Like request item of 5 spinning valve parts, by the above view it of above foundation plate, the above spinning proliferation department is forms the symmetry by the above channel department's spool thread datum.
[claim8]
7. Like request item 1 to six any item of spinning valve part, forms the plural number above spinning proliferation department in the above channel department.
[claim9]
8. Like request item 1 to six any item of spinning valve part, uses the non-partial technique to pick out the voltage.
