LADP-8 Magnetoresistance & Giant Magnetoresistance Effect

Tlhaloso e Khutšoanyane:

Sesebelisoa se fana ka mefuta e meraro ea li-sensor tsa magnetoresistance, e leng multilayer giant magnetoresistance sensor, spin valve giant magnetoresistance sensor le anisotropic magnetoresistance sensor. E thusa baithuti ho utloisisa molao-motheo le ts'ebeliso ea litlamorao tse fapaneng tsa magnetoresistance, sesebelisoa se bolokehile ebile se ts'epahala, 'me litaba tsa liteko li ruile. E ka sebelisoa tekong ea motheo ea fisiks, tekong ea sejoale-joale ea fisiks le liteko tse felletseng tsa moralo oa fisiks Likholetjheng le liunivesithing le likolong tse mahareng.

1. Utloisisa liphello tsa magneto-resistance le ho lekanya matla a khoheliR_bea lisebelisoa tse tharo tse fapaneng.

2. Setšoantšo sa polane eaR_b/R₀kaB'me u fumane boleng bo phahameng ba phetoho e amanang le khanyetso (R_b-R₀)/R₀.

3. Ithute ho lekanya li-sensor tsa magneto-resistance le ho bala kutlo ea lisensara tse tharo tse hanyetsanang le magneto.

4. Lekanya motlakase o hlahisoang le motlakase oa li-sensor tse tharo tsa magneto-resistance.

5. Etsa moralo oa "magnetic hysteresis loop" ea spin-valve GMR.
