LADP-8 Magnetoresistance & Giant Magnetoresistance Effect

Kufotokozera Kwachidule:

Chidachi chimapereka mitundu itatu ya masensa a magnetoresistance, omwe ndi multilayer giant magnetoresistance sensor, spin valve giant magnetoresistance sensor ndi anisotropic magnetoresistance sensor. Chimathandiza ophunzira kumvetsetsa mfundo ndi kagwiritsidwe ntchito ka zotsatira zosiyanasiyana za magnetoresistance, chidachi ndi chotetezeka komanso chodalirika, ndipo zomwe zili mu kuyeserako ndi zambiri. Chingagwiritsidwe ntchito mu kuyesera koyambira kwa fizikisi, kuyesa kwamakono kwa fizikisi komanso kuyesa kwathunthu kwa fizikisi m'makoleji ndi mayunivesite ndi masukulu a sekondale.

Zoyesera

1. Kumvetsetsa zotsatira za kukana kwa maginito ndi kuyeza kukana kwa maginitoR_bya zinthu zitatu zosiyana.

2. Chithunzi cha chidule chaR_b/R₀ndiBndipo pezani mtengo wapamwamba kwambiri wa kusintha kwa kukana (R_b-R₀)/R₀.

3. Phunzirani momwe mungasinthire masensa okana maginito ndikuwerengera mphamvu ya masensa atatu okana maginito.

4. Yesani mphamvu ya magetsi yotuluka ndi mphamvu ya masensa atatu okana maginito.

5. Konzani lupu ya magnetic hysteresis ya GMR yozungulira-valavu.
