LADP-19 Magnetoresistance & Giant Magnetoresistance Aafiaga
O le mea faigaluega tuʻuina mai tolu ituaiga o magnetoresistance sensors, o multilayer lapisi magnetoresistance sensor, vili alatoto lapoʻa magnetoresistance sensor ma anisotropic magnetoresistance sensor. E fesoasoani i tamaiti aʻoga malamalama i le mataupu faʻavae ma le faʻaogaina o eseʻese magnetoresists aafiaga, o le mea faigaluega e saogalemu ma faʻatuatuaina, ma o le faʻataʻitaʻiga mataupu e mauoa. E mafai ona faʻaaogaina ile faʻataʻitaʻiga o le fisiki, faʻataʻitaʻiga o mea faʻaonapo nei ma faʻataʻitaʻiina le fisiki faʻapitoa i Kolisi ma iunivesite ma aʻoga tulaga lua.
Faʻataʻitaʻiga
1. Malamalama i aafiaga magneto-teteʻe ma fua le teteʻe maneta Rb o mea eseese e tolu.
2. Ata o le ata Rb/R0 ma B ma maua le sili aoga o teteʻe faʻatatau suiga (Rb-R0) /R0.
3. Aʻoaʻo pe faʻafefea ona faʻatonuina le magneto-resistors sensor & fuafua le maaleale o le tolu magneto-resistors sensor.
4. fua le volitiga galuega faatino ma le taimi nei o tolu magneto-tetee sensor.
5. Fuafua le maneta hysteresis matasele o se viliina-alatoto GMR.
