Sharaxaada Xoogga
Neodymium waa bir antiferromagnetic ah oo soo bandhigta sifooyin birlab ah marka ay saafi tahay, laakiin kaliya heerkulka ka hooseeya 19 K (254.2 ° C; 425.5 ° F). Xeryahooda Neodymium ee leh biraha kala-guurka ferromagnetic sida birta, oo leh heerkulka Curie in ka badan heerkulka qolka, ayaa loo isticmaalaa in lagu abuuro magnets neodymium.
Neodymium magnets 'xoogga waa isku-darka waxyaabo kala duwan. Midda ugu muhiimsan waa anisotropy uniaxial magnetocrystalline aadka u sarreeya ee qaab dhismeedka tetragonal Nd2Fe14B (HA 7 T - xoogga goobta magnetic H ee cutubyada A/m ee ka dhanka ah daqiiqada magnetic ee Am2). Tani waxay tusinaysaa in crystal walaxda magnetizes door bidaan iyada oo la raacayo dhidibka crystal gaar ah laakiin waxa ay u arkaan in ay aad u adag in magnetize jihooyin kale. Daawaha magnetka neodymium, sida magnets kale, wuxuu ka samaysan yahay miraha microcrystalline kuwaas oo inta lagu guda jiro wax soo saarka ku toosan beer xoog leh oo birlab ah sida faashashahooda magnetic dhammaan waxay tilmaamayaan isla jihada. Xaruntu waxay leedahay qasabad aad u saraysa, ama iska caabin demagnetization, taas oo ay ugu wacan tahay caabbinta shabagga crystal ee beddelka jihada birlabta.
Sababtoo ah waxay ka kooban tahay afar elektaroonik ah oo aan la wadaagin qaab dhismeedka elektarooniga ah marka la barbar dhigo (celcelis ahaan) seddex bir ah, atomka neodymium wuxuu awoodaa inuu yeesho daqiiqad dipole magnetic weyn. Elektaroonnada aan lammaane ahayn ee magnet-ka ku jira ee isku toosan si ay wareeggoodu u jeeddaan isla jihada ayaa soo saara goobta magnetic. Tani waxay keenaysaa magnetization cufan xoog leh ee isku dhafka Nd2Fe14B (Js 1.6 T ama 16kG) iyo magnetization-ka caadiga ah ee 1.3 teslas. Natiijo ahaan, wejigan magnetic wuxuu leeyahay awood uu ku kaydiyo xaddi badan oo tamarta magnetic (BHmax 512 kJ/m3 ama 64 MGOe), maadaama cufnaanta tamarta ugu sareysa ay la mid tahay Js2.
Qiimaha tamarta magnetic waa qiyaastii 18 jeer mug iyo 12 jeer cuf ka weyn "caadiga ah"magnets ferrite. Samarium cobalt (SmCo), Magnet-ka dhulka dhifka ah ee ganacsi ahaan loo heli karo, wuxuu leeyahay heer ka hooseeya habkan tamarta birlabeedka marka loo eego NdFeB alloys. Astaamaha magnetic Neodymium magnets-ka waxaa si dhab ah u saameeya qaab-dhismeedkooda yar-yar ee alloy-ga, habka wax-soo-saarka, iyo halabuurka.
Atamyada birta iyo isku darka neodymium-boron ayaa laga helaa lakabyo kale oo gudaha qaab dhismeedka crystal Nd2Fe14B. Atamyada boron-ka diamagnetic waxay kor u qaadaan isku-xidhnaanta iyada oo loo marayo curaarta covalent ee xooggan laakiin si toos ah ugama qayb qaataan magnetismka. Neodymium magnets waa ka qaalisan yihiin magnets-ka samarium-cobalt sababtoo ah isku-duubnaanta dhulka naadirka ah ee hooseeya (12% mugga, 26.7% cufka), iyo sidoo kale helitaanka neodymium iyo birta marka loo eego samarium iyo kobalt.

Dhibaatooyinka Daxalka
Xuduudaha hadhuudhka ee birlab-ku-daran ayaa si gaar ah ugu nugul daxalka Nd2Fe14B. Daxalka noocaan ah wuxuu keeni karaa dhaawac weyn, sida nabarrada lakabka sare ama burburka magnetka oo noqda budo ah qaybo birlab ah oo yaryar.
Badeecooyin badan oo ganacsi ayaa wax ka qabta khatartan iyaga oo ku dara daboolka ilaalinta si loo joojiyo soo-gaadhista deegaanka. Dheecaannada ugu caansan waa nikkel, nikkel-copper-nickel, iyo zinc, halka biraha kale sidoo kale loo isticmaali karo, sida polymer iyo lacquer ilaalinta.dahaarka.
Saamaynta Heerkulka
Neodymium wuxuu leeyahay isugeyn taban, taasoo ka dhigan in marka heerkulku kor u kaco, labadaba xoogga iyo cufnaanta tamarta magnetic (BHmax) labadaba. Heerkulka deegaanka, birta neodymium-iron-boron magnets waxay leeyihiin awood xoog badan; si kastaba ha ahaatee, marka heerkulku kordho 100 °C (212 °F), qasabku si degdeg ah ayuu hoos ugu dhacayaa ilaa uu ka gaaro heerkulka Curie, oo ah ku dhawaad 320 °C ama 608 °F. Hoos-u-dhaca ku yimid isku-xidhka ayaa xaddidaya waxtarka magnet-ka ee codsiyada kulaylka sarreeya sida marawaxadaha dabaysha, matoorada isku-dhafka ah, iwm. magnet.
