Kev txhais ntawm magnetocrystalline anisotropy
Cov anisotropy ntawm kev npaj ntawm atoms hauv ib qho khoom siv lead ua ib txwm ua rau anisotropy nyob rau hauv ntau ntawm nws lub cev thiab tshuaj, thiab cov hlau nplaum yog ib qho ntawm lawv.
Qhov nkhaus magnetization ntawm ib qho siv lead ua ib qho sib nqus ua ke raws kev sib txawv cov kab hluav taws xob qhia thiab qhov sib txawv ntawm qhov nyuaj ntawm magnetization mus rau kev kub siab tau txawv. Ntawd yog, muaju nyob rau hauv tej yam kev qhia txog kab lub axis ib qho yooj yim mus rau magnetize, tab sis tsis yooj yim rau magnetize raws ib co crystal axis cov lus qhia. Qhov tshwm sim no hu ua magnetocrystalline anisotropy.
