Kub ntawm Neel qhov kub ntawm lub sijhawm sib nqus spontaneously align antiparallel thiab net magnetization ntawm cov khoom yog xoom vim tias tus neeg sib nqus lub sijhawm nyob rau hauv sublattices tshem tawm [4]. Cov khoom hloov pauv hloov nyob ib puag ncig Neel qhov kub thiab txias raws li pom hauv daim duab 4.
Néel kub piav qhia yog dab tsi?
Lub npe hu ua Néel qhov kub thiab txias tau raug hu ua tom qab nws tus neeg nrhiav pom Louis Néel, tus kws kho mob Fab Kis uas tau txais Nobel nqi zog xyoo 1970.
Yuav ua li cas sib nqus susceptibility nrog kub?
Paramagnetic susceptibility yog inversely proportional rau tus nqi ntawm qhov kub thiab txias. Qhov kub thiab txias ua rau ntau dua thermal co ntawm atoms, uas cuam tshuam nrog kev sib nqus ntawm cov dipoles.
Dab tsi tshwm sim saum Néel kub?
Saum toj no qhov ntsuas kub hu ua Néel kub,cua sov ua kom puas tsuaj rau kev sib piv, thiab cov khoom tom qab ntawd dhau los ua paramagnetic.
Néel thiab Curie kub yog dab tsi?
Qhov sib txawv tseem ceeb ntawm Curie kub thiab Neel kub yog qhov kub ntawm Curie yog qhov kub ntawm cov khoom uas qee yam khoom poob lawv cov khoom sib nqus mus tas li whereas Neel kub yog qhov kub siab tshaj qhov uas qee yam antiferromagneticCov ntaub ntawv dhau los ua paramagnetic.

Thaum kub taub hau hypothalamic tus ntsuas kub tau rov pib ncaj qha los ntawm?
Thaum cov kab mob raug rhuav tshem los ntawm phagocytic leukocytes, cov tshuaj hu ua endogenous pyrogens raug tso rau hauv cov ntshav. Cov pyrogens ncig mus rau hypothalamus thiab rov pib dua lub ntsuas sov. Qhov no tso cai rau lub cev qhov kub thiab txias hauv qhov uas feem ntau hu ua kub taub hau.
Ntawm qhov ntsuas kub ntawm qhov ntsuas kub emf yuav yog?
Thermo emf nce mus rau qhov siab tshaj plaws ntawm qhov kub thiab txias (θ ) hu ua nruab nrab kub thiab maj mam txo thiab nws thiaj li ua zero ntawm qhov kub (θ 1) hu ua inversion temperature. Tshaj li qhov kub ntawm inversion, Thermo emf hloov kos npe thiab tom qab ntawd nce.
Ntawm khoom qab zib tsoo dab tsi yog cov kub kub?
Gold (tseem hu ua Gold Bars) yog tus nqi txiaj ntsig zoo hauv Candy Crush Saga. Tsis muaj qhov kev txiav txim qis qis dua hauv Candy Crush Saga, tab sis Qab Zib Tsob Ntoo tuaj yeem suav tias zoo ib yam li nws. Cov dej qab zib tau raug txiav tawm ntawm qhov kev ua si thaum Lub Peb Hlis 2020.
Dab tsi yog ntshav ntawm tus dev thaum tshav kub kub?
Qhov paug qhov chaw mos yuav hloov xim thiab zoo li lub voj voog mus. Thaum xub thawj, cov paug tawm los ntshav heev, tab sis raws li hnub dhau mus, nws maj mam dhau los ua dej thiab paj yeeb-liab xim. Dab lub sijhawm ntshav zoo li cas?
Dab tsi yog qhov kub kub tsis yog kab lus?
Thiab dab tsi yog qhov kub hnyiab tsis yog? Ib yam lus piav qhia uas nres qhov yeeb yam tiav ib nrab lub sijhawm nws tuaj yeem yog. Auj thov txim, "Qhov Chaw Zoo!" Txawm li cas los xij, nkawm niam txiv tuaj yeem txiav txim siab nres txhua lub sijhawm ntawm qhov kev txav mus los uas lawv muaj, tso nyiaj rau txhua yam khoom plig uas lawv tau yeej txog tam sim no.
