Magnetoresistor wani ne?

Ma'ana: Idan yadda zafi na kayayyakin da kuma abubuwan mutanen gine-gine ke ci gaba a kan tashin magana, wannan alamar zafi shi ne ake kira alamun magnetoresistance. Abubuwa masu wannan alama suna kira magnetoresistors. A cikin haka, magnetoresistor shine wata kayan aiki mai zafi da take yi lalle da tsari da karamin tashin magana.

Magnetoresistors suna da muhimmanci sosai wajen neman abin da tashi mai magana, kula daya da kuma tabbatar da yawan tashin magana. Suna koyarwa daga abubuwan gine-gine kamar indium antimonide ko indium arsenide, wadanda suka da sifatin kawo-karfi masu mahimmanci wajen magance tashin magana.

Tsarin Aiki na Magnetoresistor

Aiki na magnetoresistor ya danganta da siffar electrodynamics. Daga wannan siffar, takarda ta kasuwanci a kan kayan aiki mai magana a tashin magana zai iya canza yawan kasuwanci. Idan bai ba da tashin magana, makaicin adadin kaya a cikin magnetoresistor za su yi aiki a kan yanayi mai sauƙi.

Amma, idan tashin magana ya faru, yawan kasuwanci ya canzawa kuma ya faru a kan yanayi mai sauƙi. Yanayin mai sauƙi na kasuwanci ya zama da yawan kasa, wanda ya haɗa da kusa. Kusan kusa suna ƙara samun zafi a cikin magnetoresistor. Ba a gudanar da adadin adadin kaya masu ƙasance ba, saboda haka, an rarrabe adadin kasuwanci da ke fitowa a cikin magnetoresistor.

Ziyartar makaicin kaya a cikin magnetoresistor ya danganta da kyakkyawar makaicin kaya. Kyakkyawar makaicin kaya a cikin abubuwan gine-gine yana da ƙarin zuwa abubuwan kayayyaki. Misali, kyakkyawar makaicin indium arsenide ko indium antimonide yana ƙarin zuwa 2.4 m²/Vs.

Siffafin Magnetoresistor

Kyakkyawar makaicin magnetoresistor ya danganta da tsari da tashin magana. Kurba na siffafin magnetoresistor ana bayyana a cikin tasirin.

Idan ba a ba da tashin magana, zafi na elementin magnetoresistor ya zama zero. Idan tashin magana ya faru, zafi na abubuwa ya ci gaba a kan balon b. Tashin magana ya ƙarɓe elementin magnetoresistor zuwa yanayi 45º.

Idan tashin magana ya faru, kurba ya ci gaba a kan balon C. Elementin magnetoresistor tana yi aiki a kan balon O ko kuma a kan balon b. Idan a yi aiki a kan balon b, yana nuna siffafin mai sauƙi.

Abubuwan Magnetoresistor

Magnetoresistors suna koyarwa daga uku abubuwa:

Giant Magnetoresistance (GMR)

A cikin Giant Magnetoresistance, zafi na magnetoresistor ya ƙara daɗi a lokacin da layon ferromagnetic ke ci gaba a kan ƙarshe. Amma, idan layon nan ke ci gaba a kan ƙarfin, zafi ya ƙara ci. Tsarin GMR device ana bayyana a cikin tasirin.

Extraordinary Magnetoresistance (EMR)

A cikin Extraordinary Magnetoresistance, zafi na kayan aiki yana nuna alamar ƙarin. Idan bai ba da tashin magana, zafi ya ƙara ci. Amma, idan tashin magana ya faru, zafi ya ƙara daɗi, wanda ya nuna alamar ƙarin a cikin sifatin kawo-karfi daga tashin magana.

Tunnel Magnetoresistor (TMR)

A cikin Tunnel Magnetoresistor, tushen kasuwanci ya faru a kan hanyar ƙarin. Kasuwanci yana ci gaba daga ƙarshen ferromagnetic, tare da ƙungiyar insulating. Adadin kasuwanci da take ci gaba daga ƙungiyar insulating yana ƙarin da kyakkyawar layon a kan ƙarshen ferromagnetic. Layon ƙarin ƙarshen ferromagnetic suka ƙara daɗi adadin kasuwanci, wanda yake ƙara muhimmiyar a cikin abubuwan aiki da ke amfani da precise control da kuma neman tashin magana.

Adadin kasuwanci mai ƙarin ya ci gaba idan layon ƙarshen electrodes ke ci gaba a kan ƙarshe. Amma, idan layon ƙarshen electrodes ke ci gaba a kan ƙarfin, zafi da ke fitowa a cikin layers ya ƙara ci.
