I-LADP-8 Magnetoresistance & Giant Magnetoresistance Effect

Incazelo emfushane:

Ithuluzi lihlinzeka ngezinhlobo ezintathu zezinzwa ze-magnetoresistance, okuyi-multilayer giant magnetoresistance sensor, inzwa ye-spin valve giant magnetoresistance sensor kanye nenzwa ye-anisotropic magnetoresistance.Isiza abafundi baqonde umgomo kanye nokusetshenziswa kwemiphumela ehlukene ye-magnetoresistance, ithuluzi liphephile futhi lithembekile, futhi okuqukethwe kokuhlolwa kucebile.Ingasetshenziswa esivivinyweni esiyisisekelo se-physics, isilingo sefiziksi yesimanje kanye nokuhlolwa okuphelele kwefiziksi yedizayini Emakolishi nasemanyuvesi nasezikoleni zamabanga aphezulu.

Izivivinyo

1. Qonda imiphumela ye-magneto-resistance futhi ulinganise ukumelana kazibutheR_byezinto ezintathu ezahlukene.

2. Isakhiwo somdwebo weR_b/R₀ngeBfuthi uthole inani eliphezulu loshintsho oluhlobene nokumelana (R_b-R₀)/R₀.

3. Funda ukuthi ungalinganisa kanjani izinzwa ezimelana ne-magneto futhi ubale ukuzwela kwezinzwa ezintathu ezimelana ne-magneto.

4. Kala i-voltage ephumayo kanye nesimanje sezinzwa ezintathu ezimelana ne-magneto.

5. Hlela iluphu ye-magnetic hysteresis ye-spin-valve GMR.
