LADP-8 Magnetoresistance & Giant Magnetoresistance Effect

Tlhaloso e Khutšoanyane:

Sesebelisoa se fana ka mefuta e meraro ea li-sensor tsa magnetoresistance, e leng sensor ea magnetoresistance ea multilayer, 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.
