Ferromagnetism yog vim muaj qhov sib txawv ntawm cov hlau nplaum dipole nyob rau tib qho kev taw qhia.
Yuav ua li cas cov tshuaj qhia antiferromagnetism?
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).
Yog O2 dia lossis paramagnetic?
Daim duab lub zog ntawm O2molecule yog: Cov hluav taws xob hauv π∗2Px thiab π∗2Py nyob twj ywm unpaired. Yog li, muaj ob lub electrons tsis sib xws hauv O2. Li no, nws yog paramagnetic nyob rau hauv qhovnrog ob lub electrons tsis sib xws.
Puas yog Tsis yog paramagnetic?
NO muaj cov lej khib ntawm electrons (7 + 8=15) thiab vim muaj qhov tsis sib xws ntawm electron, nws yog paramagnetic nyob rau hauv lub xeev gaseous.
Yuav ua li cas cov tshuaj hauv qab no qhia txog cov khoom tiv thaiv kab mob?
(R) MnO is an antiferromagnetic substance.
