Study on magneto-refractive effects in (CoFe)_ (1-x)Ag_x granular thin films |

| Abstract: | It is very important for magnetoelectronic devices that the giant magnetoresistance (GMR) effect is measured on-line without electrode contact. The magnetorefractive effects (MRE) in granular (CoFe) 1-xAg xthin films are studied by infrared spectroscopy technology. The results show that in the first approximation the variation of refractivity of infrared beam is proportional to that of GMR measured by conventional four-probe method, and MRE can be used as an on-line probe method to detect spin dependent GMR effects in magnetic thin films. |
