Cov yam ntxwv kub thiab kub coefficients ntawm Ferrite hlau nplaum

Ferrite hlau nplaum yog cov khoom sib nqus zoo heev nrog cov khoom sib nqus zoo. Txawm li cas los xij, raws li qhov ntsuas kub hloov pauv, cov khoom sib nqus ntawm cov hlau nplaum ferrite kuj hloov, uas yog qhov tseem ceeb rau peb kom raug siv cov khoom no.
Ua ntej, raws li qhov kub thiab txias, qhov sib nqus ntawm cov hlau nplaum ferrite maj mam txo. Qhov no yog vim hais tias ntawm qhov kub thiab txias, Thermal motion nyob rau hauv lub lattice yuav ua rau tsis muaj zog ntawm kev txiav txim ntawm cov sib nqus domains, yog li txo cov magnetization. Tsis tas li ntawd, qhov nce ntawm qhov kub thiab txias kuj tseem yuav ua rau lub zog thermal zog ntawm cov khoom, txo cov hlau nplaum anisotropy, thiab ntxiv zog rau cov hlau nplaum.
Qhov thib ob, qhov kub coefficient ntawm ferrite hlau nplaum kuj yog ib qho tseem ceeb parameter. Qhov kub coefficient yog hais txog qhov feem pua ​​​​ntawm cov kev hloov pauv hauv cov hlau nplaum ntawm cov khoom thaum lub sij hawm hloov kub. Rau cov hlau nplaum ferrite, qhov kub coefficient feem ntau yog qhov tsis zoo. Uas yog hais tias, raws li qhov kub thiab txias, lub magnetization siv nyob rau hauv magnetic teb yuav maj mam txo. Cov yam ntxwv no yog qhov tseem ceeb heev rau cov khoom siv hluav taws xob uas yuav tsum tau siv rau hauv qhov chaw kub thiab txias, thiab nws yog ib qho tsim nyog yuav tsum tau ua kom raug thiab siv cov yam ntxwv no kom ntseeg tau tias kev ua tau zoo thiab ruaj khov ntawm cov khoom siv.
ferrite hlau nplaum muaj qhov zoo intrinsic Coercivity kub coefficient (xws li ib puag ncig, nws qhov kev hloov pauv ntau ntxiv yog ntxiv rau 0.27 feem pua ​​/ degree ), thiab tsuas yog ferrite tuaj yeem qhia tus yam ntxwv no ntau heev. Txawm li cas los xij, cov khoom siv hlau nplaum yuav txo qis thaum qhov kub nce ntxiv (nws qhov tsis zoo induction kub coefficient yog -0.2 feem pua ​​/Celsius). Qhov kawg tshwm sim yog tias cov hlau nplaum ferrite tuaj yeem siv rau qhov kub thiab txias uas yuav luag tsis muaj teeb meem.
Zuag qhia tag nrho, cov yam ntxwv kub ntawm cov hlau nplaum ferrite yog cov teeb meem uas yuav tsum tau muab sau tseg hauv daim ntawv thov. Peb yuav tsum to taub nws cov magnetization thiab kub coefficient cov yam ntxwv nyob rau hauv thiaj li yuav zoo dua siv cov khoom no, thaum them nyiaj mloog mus rau tsim nyog ntsuas kub kom tsis txhob muaj ib tug txo nyob rau hauv kev ua tau zoo ntawm cov hlau nplaum nyob rau hauv high kub. Hauv kev siv, peb tuaj yeem ua kom ntseeg tau tias kev ua haujlwm thiab kev pabcuam lub neej ntev ntawm cov ntaub ntawv los ntawm kev xaiv cov hlau nplaum ferrite uas tsim nyog thiab tswj qhov kub thiab txias.
