Tungsten yog cov khoom siv ua tsis tau, tsis yog ferromagnetic ib. Nws cov hlauetism tau tsim los ntawm Spins ntawm cov hluav taws xob hluav taws xob plhaub, tab sis kev sib cuam tshuam ntawm cov hlau nplaum tsis muaj zog, tiv thaiv kev tsim macroscopic motetization.
Thaum tshawb nrhiav lub ntiaj teb sib nqus ntawm cov ntaub ntawv sib nqus ntawm cov ntaub ntawv, peb feem ntau ntsib ntau hom sib nqus, xws li Paramagnetism thiab Ferromagnetism thiab Ferromagnetism thiab Ferromagnetism thiab Ferromagnetism thiab Ferromagnetism thiab Ferromagnetism thiab Ferromagnetism thiab Ferromagnetism Yog li, Magnetism li cas cov hlau tungsten zwm?
Ua ntej, peb yuav tsum tau qhia meej cov ntsiab lus tseem ceeb ntawm paramagnetism thiab Ferromagnetism. Cov ntaub ntawv paramagetic yog cov khoom siv uas, nyob rau hauv ib qho kev sib nqus ntawm cov atoms los yog cov qauv sib nqus ntawm cov kev taw qhia ntawm daim teb, ua rau muaj qhov tsis muaj zog magnetism. Ferrosnnetic cov ntaub ntawv, ntawm qhov tod tes, muaj cov muaj zog dua hlau nplaum thiab tuaj yeem ua rau Macroscopic hauv qhov tsis muaj peev xwm ua ntawv sib nqus. Cov hlau nplaum ua pov thawj kev sib raug zoo ntawm lub zog ntawm lub zog ntawm kev sib nqus thiab lub zog ntawm lub teb.
Rau cov xim hlau teeb tungsten, nws cov khoom sib nqus yog feem ntau paramagnetic. Qhov no yog vim tias hluav taws xob kev npaj ntawm tungsten atoms cov txiaj ntsig nyob rau hauv qee tus lej ntawm hluav taws xob hluav taws xob, thiab cov tshuab hluav taws xob hauv cov plhaub tsis sib xyaw no tuaj yeem tsim cov kev sib nqus. Txawm li cas los xij, tsis zoo li cov ntaub ntawv ferromagnetic, lub sijhawm sib nqus ntawm tungsten attract tsis muaj cov qauv sib nqus thiab, tsis muaj zog macroscopic magnetism. Nyob rau hauv tus ntawm kev sib nqus sab nraud sib nqus daim teb, cov kev sib nqus ntawm tungsten me ntsis sib dhos me ntsis ntawm cov kev coj ua ntawm cov nyhuv, ua rau muaj cov nyhuv tsis muaj zog.
Kom tau txais kev nkag siab tob ntawm Tupsten cov khoom hauv Paramagnetic, peb tuaj yeem kuaj xyuas cov hauv qab no:
1. Hluav Taws Xob Hluav Taws Xob thiab lub zog sib nqus
Raws li kev hloov pauv hlau, tungsten muaj cov txheej txheem hluav taws xob nyuaj. Hauv ib feem puv hluav taws xob plhaub, lub spins ntawm electrons tsim cov magents sib nqus. Cov sijhawm no yog qhov tsis muaj kev cuam tshuam ntawm cov chaw sib nqus sab nraud, tab sis ib zaug ua ib qho kev sib nqus tau siv, lawv tau ua tiav me ntsis los ntawm kev sib nqus.
2. Kev sib cuam tshuam ntawm lub sijhawm sib nqus
Txawm hais tias tungsten atoms muaj lub sijhawm sib nqus, cov kev sib cuam tshuam ntawm lawv lub sijhawm yog tsis muaj zog. Qhov kev sib txig sib luag nrog cov qauv sib nqus hlau sib xyaw hauv cov ntaub ntawv ferromagnetic. Hauv cov ntaub ntawv ferromagnetic, cov kev sib cuam tshuam ntawm cov sib nqus uas nyob ib puag ncig tuaj yeem ua rau muaj macroscopic magnetism hauv cov khoom siv. Txawm li cas los xij, tungsten tsis tuaj yeem tsim cov qauv sib nqus sib nqus no vim muaj kev cuam tshuam tsis muaj zog ntawm nws cov kev sib nqus.
3. Macroscopic tus cwj pwm
Vim tias qhov kev sib cuam tshuam ntawm Tungsten lub sijhawm sib nqus tsis muaj zog thiab tsis tuaj yeem tsim cov nyhuv macroscopic, nws tsuas yog cov nyhuv tsis muaj zog nyob rau hauv cov khoom siv sib nqus. Cov nyhuv no yog qhov tseem ceeb piv rau lub zog sib luag los ntawm cov ntaub ntawv ferromagnetic.
