Property and application of permalloy magnetoresistance sensor 坡莫合金磁阻传感器的特性研究和应用
We also find that the pinning phenomenon gradually disappear with thicker single layer of the [ pt / mn ] n films , and firstly prepared permalloy before the deposition of [ pt / mn ] n multiplayer more easily form anti - ferromagnetic structure than another caseo maybe this is a good way to shorten the annealing time 我们还发现随着单层厚度的增加钉扎现象逐渐消失,而且先沉积nife层,后沉积pt / mn多层膜的情形更容易获得反铁磁结构。这可能是缩短退火时间的一种好方法。
Permalloy is a nickel-iron magnetic alloy, with about 20% iron and 80% nickel content. Invented in 1914 by physicist Gustav Elmen at Bell Telephone Laboratories, it is notable for its very high magnetic permeability, which makes it useful as a magnetic core material in electrical and electronic equipment, and also in magnetic shielding to block magnetic fields.
