LADP-8 Magnetoresistance & Giant Magnetoresistance Effect

Kev Piav Qhia Luv:

Cov cuab yeej no muaj peb hom magnetoresistance sensors, uas yog multilayer giant magnetoresistance sensor, spin valve giant magnetoresistance sensor thiab anisotropic magnetoresistance sensor. Nws pab cov tub ntxhais kawm nkag siab txog lub hauv paus ntsiab lus thiab kev siv ntawm ntau yam magnetoresistance effects, cov cuab yeej no muaj kev nyab xeeb thiab txhim khu kev qha, thiab cov ntsiab lus ntawm kev sim yog nplua nuj. Nws tuaj yeem siv rau hauv kev sim physics yooj yim, kev sim physics niaj hnub thiab kev sim physics tsim qauv hauv cov tsev kawm qib siab thiab tsev kawm ntawv theem nrab.
