LADP-19 Magnetoresistance & Giant Magnetoresistance Zotsatira
Chidacho chimapereka mitundu itatu yama sensa a magnetoresistance, omwe ndi kachipangizo kakang'ono kwambiri kosakanikirana ndi maginito, kachipangizo kamene kamagwiritsira ntchito magetsi ndi magetsi a magnetoresistance. Zimathandiza ophunzira kumvetsetsa mfundo ndi momwe angagwiritsire ntchito mphamvu zotsutsana ndi magetsi, chidacho ndi chodalirika komanso chodalirika, ndipo zoyeserera zake ndizolemera. Itha kugwiritsidwa ntchito poyesa kuyesayesa kwa fizikiki, kuyeserera kwamakono kwa sayansi yaukadaulo komanso kuyeserera kokwanira kwa fizikiki m'makoleji ndi mayunivesite ndi masekondale.
Zoyesera
1. Mvetsetsani zovuta zotsutsana ndi maginito ndikuyesa maginito kukana Rb za zinthu zitatu zosiyana.
2. Chithunzi cha chiwembu cha Rb/R0 ndi B ndikupeza kuchuluka kwakusintha kwakusintha kwakanthawi (Rb-R0) /R0.
3. Phunzirani momwe mungagwiritsire ntchito masensa osagwiritsa ntchito magneto & kuwerengera kutengeka kwa masensa atatu a magneto-resistance.
4. Yesani kutulutsa kwamphamvu ndi magetsi amakono atatu olimbana ndi maginito.
5. Konzekerani maginito a hysteresis a spin-valve GMR.
