SPIN ACCUMULATION ELEMENT COMPRISING SPIN CURRENT CONSTRICTION LAYER, AND MAGNETIC SENSOR |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a spin accumulation element having a high output, high resolution, and low noise performance. <P>SOLUTION: The spin current constriction layer 405 is provided between a magnetic conductor 406 for detecting voltage and a nonmagnetic conductor 401. Only spin current flows in the spin current constriction layer. Constricting the spin current can prevent the flow of the spin current in the extra part other than a scattering component causing an change in resistance to dramatically improve a detecting efficiency of the spin accumulation element. <P>COPYRIGHT: (C)2008,JPO&INPIT |
