I-LADP-19 Magnetoresistance & Giant Magnetoresistance Effect
Ithuluzi lihlinzeka ngezinhlobo ezintathu zezinzwa ze-magnetoresistance, eziyizinzwa ze-multilayer giant magnetoresistance, inzwa ye-spin valve giant ye-magnetoresistance kanye ne-anisotropic magnetoresistance sensor. Kuyasiza abafundi ukuthi baqonde umgomo kanye nokusetshenziswa kwemiphumela ehlukile ye-magnetoresistance, insimbi iphephile futhi inokwethenjelwa, futhi okuqukethwe kokuhlolwa kucebile. Ingasetshenziswa ekuhlolweni okuyisisekelo kwe-physics, ukuhlolwa kwe-physics yanamuhla nokuhlolwa okuphelele kwe-physics kumaKholeji nasemayunivesithi nasezikoleni zamabanga aphakeme.
Ukuhlolwa
1.Qonda imiphumela emelana nemagneto futhi ulinganise ukumelana namandla kazibuthe Rb kwezinto ezintathu ezahlukene.
2. Umdwebo wesakhiwo se Rb/R0 nge B bese uthola inani eliphakeme lokuphikisana nesihlobo sokumelana (Rb-R0) /R0.
3. Funda ukuthi ungalinganisa kanjani izinzwa zokumelana ne-magneto & ubale ukuzwela kwezinzwa ezintathu ze-magneto-resistance.
4. Linganisa i-voltage yokukhipha kanye nesikhathi samanje sezinzwa ezintathu zemagineto.
5. Hlela isakhiwo se-magnetic hysteresis loop se-spin-valve GMR.
