Yog li nws muaj lub sijhawm sib nqus siab tshaj plaws ntawm 3d cov ntsiab lus thiab muaj tus nqi ntawm cov hlau nplaum sib nqus ntau dua li xoom. Yog li MnO yog antiferromagnetic thiab qhov kev xaiv raug yog B. Lus Cim: Cov hlau zoo li Fe, Co thiab Ni qhia ferromagnetism tab sis thaum lawv tsim qee cov tebchaw, lawv cov cwj pwm sib nqus hloov.

Is MnO antiferromagnetic tshuaj?

Antiferromagnetism , hom hlau nplaum hauv cov khoom xws li manganese oxide (MnO) uas nyob ib sab ions uas coj li cov hlau nplaum me me (qhov no manganese ions, Mn 2+) spontaneously dlhos lawv tus kheej ntawm qhov tsis tshua muaj kub mus rau opposite, los yog antiparallel, kev npaj thoob plaws hauv cov khoom kom nws nthuav tawm …

Yuav ua li cas hom hlau nplaum qhia los ntawm MnO?

Cov nanoclusters ntawm cov hlau oxides tau txais txiaj ntsig zoo vim tias lawv tau pom qhov tus cwj pwm ferromagnetic txawm tias lawv yog antiferromagnetic nyob rau hauv ntau theem. Ib yam li ntawd, MnO nanoclusters tau kwv yees ua ferromagnetic los ntawm txoj kev xav1 txawm tias lawv cov theem ntau yog antiferromagnetic.

Ferrimagnetism yog dab tsi thiab nws qhov piv txwv?

Cov khoom siv ferrimagnetic yog cov khoom siv uas muaj cov pej xeem ntawm atoms nrog kev tawm tsam lub sijhawm sib nqus , zoo li hauv antiferromagnetism. … Piv txwv li no tuaj yeem tshwm sim thaum cov pej xeem sib txawv ntawm cov atoms lossis ions (xws li Fe2+ thiab Fe3 +). Ferrimagnetismtau feem ntau tsis meej pem nrog ferromagnetism.

Cov tshuaj twg qhia tias muaj tshuaj tiv thaiv kab mob?

Cov ntaub ntawv Antiferromagnetic tshwm sim feem ntau ntawm cov hlau hloov pauv, tshwj xeeb tshaj yog oxides. Piv txwv xws li hematite, hlau xws li chromium, alloys xws li hlau manganese (FeMn), thiab oxides xws li nickel oxide (NiO).
