Ferromagnetism tau pom nyob hauv kev hloov pauv hlau thiab qee qhov ntawm lawv cov tebchaw . Nyob rau hauv antiferromagnetism, lub sij hawm sib nqus taw tes nyob rau hauv qhov opposite kev taw qhia. Vim li no, qhov sib nqus susceptibility ntawm ib yam khoom txo qis rau qee qhov. Antiferromagnetism pom nyob rau hauv cov ntsev ntawm ions xws li Mn+2, Fe+ 3
Yuav ua li cas cov khoom qhia ferromagnetism?
Ferromagnetism yog ib hom hlau nplaum uas cuam tshuam nroghlau, cob alt, npib tsib xee, thiab qee cov alloys lossis cov tebchaw muaj ib lossis ntau ntawm cov ntsiab lus no. Nws kuj tshwm sim hauv gadolinium thiab ob peb lwm yam tsis tshua muaj hauv ntiaj teb.
Yuav ua li cas koj thiaj paub yog tias ib yam khoom yog ferromagnetic?
Cov khoom ntawm Ferromagnetic Khoom
Cov atoms ntawm cov tshuaj ferromagnetic muaj tas mus li dipole tam sim no nyob rau hauv cov thawj. Atomic dipoles nyob rau hauv ferromagnetic tshuaj yog taw qhia nyob rau hauv tib txoj kev raws li sab nraud magnetic teb. Lub sijhawm sib nqus dipole yog qhov loj thiab nyob rau hauv cov kev taw qhia ntawm magnetizing teb.
Cov tshuaj hauv qab no twg yog ferromagnetic?
Iron, cob alt, nickel thiab CrO2 yog hu ua ferromagnetic tshuaj.
Yuav ua li cas yog ib yam khoom qhia Ferrimagnetism?
Yog li, cov tshuaj ferrimagnetic qhia tau zoo dua cov hlau nplaum zoo dua li cov tshuaj tiv thaiv ferromagnetic vim lawv muaj qhov tsis yog xoom net magnetic dipoleib pliag.. Piv txwv ntawm Antiferromagnetic tshuaj muaj xws li hematite, hlau xws li chromium, alloys xws li FeMn (hlau manganese), thiab oxides xws li NiO (nickel oxide).
