TMR Sensor Magnet

Qee Qhov Taw Qhia ntawm TMR sensor

TMR sensor yog lub sijhawm ua magnetoresistance effect sensor uas tau siv rau kev lag luam hauv xyoo tas los. TMRsensor muaj qhov hloov pauv ntau dua piv rau AMR thiab GMR sensor, yog li tau txais ntau yam txiaj ntsig suav nrog tus nqi qis thiab kev siv hluav taws xob, kev teb ntau zaus thiab rhiab heev. Hongyu kuj tau sau qee qhov kev paub dhau los hauv TMR sensor hlau nplaum vim tias siv dav ntawm TMR sensor.

Tunneling Magnetoresistance Effect yog dab tsi?

Sandwich qauv ua los ntawm ob txheej ferromagnetic thiab insulating txheej tuaj yeem hu ua magnetic tunnel junctions (MTJs). Tunneling magnetoresistance ntawm MTJs yuav raug hloov thaum hloov tus txheeb ze orientation ntawm ob ferromagnetic txheej lub sij hawm sib nqus, thiab qhov tshwm sim no hu ua tunneling magetoresistance (TMR) nyhuv. Cov qauv ntawm TMR thiab GMR tivthaiv yog qhov zoo ib yam, thiab tam sim no kev taw qhia ntawm TMR thiab GMR tivthaiv yog perpendicular thiab parallel rau txheej feem.

Lub magnetization kev taw qhia ntawm cov pinned txheej yog tsau, thiab magnetization kev taw qhia ntawm lub dawb txheej yuav tsum tau kho raws li sab nraud magnetic teb, yog li ntawd, hluav taws xob tiv thaiv ntawm TMR tivthaiv kuj yuav hloov. TMR tivthaiv qhia qhov tsawg kawg nkaus tiv thaiv ib zaug magnetization kev taw qhia ntawm cov dawb txheej yog parallel mus rau pinned txheej'sand ces high-tam sim no ntws los ntawm lub barrier. Hloov chaw, kev tiv thaiv yuav nce ntxiv thaum magnetization kev taw qhia antiparallel, yog li me ntsis tam sim no ntws los ntawm qhov thaiv.

Hais txog TMR Sensor Magnet

Pab pawg Hongyu yuav pab cov neeg siv khoom xaiv qhov tsim nyog TMR sensor raws li cov ncauj lus qhia ntxaws ntxaws, thiab tos ntsoov koom tes nrog cov neeg siv khoom cuam tshuam.
