Lub luag haujlwm ntawm cov hlau Gd thiab hlau Ho hloov Nd

Ntawm cov hlau hnyav hauv ntiaj teb, Gd muaj cov peev txheej ntau tshaj plaws, thiab Gd kuj tuaj yeem tsim tau Gd2Fe14B sib txuas. Lub zog sib nqus polarization Js thiab anisotropic teb HA ntawm cov sib tiv no yog qhov qis dua, tab sis nws cov Curie kub Tc yog qhov ntau tshaj. Vim tias muaj qhov tshwj xeeb muaj txiaj ntsig ntawm Gd thiab tus nqi qis, qee cov tuam ntxhab ntxiv Gd nyob rau hauv daim ntawv ntawm gadolinium-iron alloy mus rau qee qhov hloov Nd mus tsim cov khoom lag luam qis ua lag luam NdFeB. Txawm li cas los xij, nws siv tswv yim ntawm Gd los hloov Nd yog khib nyiab. Thaum nws tshawb pom tias Gd muaj qhov tseem ceeb siv ntau dua yav tom ntej, nws yuav pom tias yog ib qho tsis muaj kev cuam tshuam. Hloov chaw Ho rau Nd muaj tib qho teebmeem thiab teeb meem.
