MAGNITNOKShAVI

MAGNITNOKShAVI, prosesshoe, ki dar ferromagnetikho hangomi tasiri maydoni magnitii beruna ba vujud omada, magnitnokii ferromagnetikro dar samti maydon afzun mekunand. Dar holati bemagnitshavii purra namunai ferromagniti az sohahoi na on qadar kalon (domennoy hajmashon 10-*—.10-* sm3, bazan to 10-3 sm3) iborat ast, ki har yake to sershavi (/,) magnitnok shudaast. Ammo dar in hol vektorhoi khud az khud magnitnokshavii domenho (/,) tavre joy megirand, ki momenti Magnitii natijavii namuna / = 0 ast. Magnitnokshavi hodisai az nav orientasiyashavii vektorhoi magnitnokii domenho dar samti maydoni tasirkunanda meboshad; on prosesshoi joyivazkuni, davrzani, va paraprosessro dar bar megirad. Prosessi joyivazkuni dar ferromagnetikhoi serdomen az joyivazkunii hududhoi bayni domenho iborat ast; hajmi domevhoe, ki vektorhoyashon (/ya) bo samti shiddatnokii maydoni magniti (Ya) kunji khurdtarinro tashkil medihand, az hisobi domenhoi hamsoya, ki nisbat ba maydon az jihati energetiki kamtar samt dorand, meafaoyad. Ba samti maydon N tob khurdan nvektorhoi 19 prosessi davrzani buda, ba anizotroniyai magnitii ferromagnetikho vobasta meboshad. Paraprosess qad-qadi maydon saf kashidani momenthoi oddii magniti meboshad, ki onho bo tasiri harakati garmi dar domenho nisbat ba samti 1L ba digar taraf mayl kardaand.
