Antiferromagnetic cov ntaub ntawv txhim kho txoj kev cov ntaub ntawv sau thiab nyeem hluav taws xob hauv cov khoom siv. Lawv yog cov hlau nplaum microscopic uas muaj qhov sib txawv.
Yuav siv dab tsi ntawm antiferromagnetic?
Cov hlau nplaum yog qhov siv tau zoo hauv lub neej txhua hnub los ntawm cov hlau nplaum ntawm lub tub yees mus rau cov hlau nplaum sib nqus nyob tom qab ntawm daim npav rho nyiaj. Ob qho piv txwv no yog cov piv txwv ntawm cov hlau nplaum nyuaj, txhais tau tias lawv khaws lawv cov hlau nplaum yooj yim thiab yog li muaj txiaj ntsig zoo hauv cov ntaub ntawv nco txog.
Vim li cas antiferromagnetism tshwm sim?
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, Mn2 +) spontaneously dlhos lawv tus kheej ntawm qhov tsis tshua muaj kub mus rau qhov opposite, los yog antiparallel , kev npaj thoob plaws hauv cov khoom kom nws nthuav tawm …
Dab tsi yog cov khoom siv tshuaj tiv thaiv kab mob?
Cov ntaub ntawv uas nthuav tawm cov tshuaj tiv thaiv kab mob hu ua antiferromagnetic khoom. … Cov ntaub ntawv antiferromagnetic feem ntau pom nyob rau hauv cov kev hloov pauv hlau tebchaw. Hematite, chromium, alloys ntawm hlau manganese thiab oxides ntawm nickel yog cov piv txwv ntawm cov khoom siv tshuaj tiv thaiv.
Dab tsi yog qhov txawv ntawm antiferromagnetism thiab Diamagnetism?
yog tias diamagnetic yog ib yam khoom uas nthuav tawm diamagnetism thaum antiferromagnetism yog (physics) ib qho tshwm sim, zoo ib yam li ferromagnetism, nyob rau hauv uas sib nqus domains kab nyob rau hauv ib tug tsis tu ncua qauv, tab sis nrog nyob sib ze electron spin taw tes nyob rau hauv opposite lus qhia; cov ntaub ntawv uas qhia cov nyhuv no yog…
