- A theoretical model inoratidza kuti simba remagineti rechiedza rinopesvedzera zvakananga kuita kweFaraday.
- Mupiro wakaverengwa unosvika ~ 17% muchiedza chinooneka uye kusvika ku70% mu infrared yeTGG.
- Chidzidzo ichi chakavakirwa paLandau-Lifshitz-Gilbert equation uye inoburitswa mukati Mishumo yeSainzi.
- Zvinogoneka maapplication: advanced optics, spintronics uye quantum tekinoroji muEurope.
Tsvagiridzo mukudyidzana pakati pechiedza uye nyaya yakawedzera chidimbu chisingatarisirwe: the magnetic field yechiedza Inobatsirawo kuFaraday effect.kwete chete chikamu chayo chemagetsi, maererano nekudzidza yakasainwa nechikwata kubva kuHebrew University yeJerusarema.
Zvabuda, Yakaburitswa munaNovember 20, 2025 mu magazini Mishumo yeSainziVanotsigira izvi neoretical modhi iyo Chiedza chinogona kugadzira magineti torque mune zvinhukuyera basa rayo nenhamba dzakakosha: inenge 17% yekutenderera munzvimbo inooneka y kusvika ku70% mu infrared.
Chii chinochinja mumaonero atinoita Faraday?
Munguva anenge mazana maviri emakore Zvaifungidzirwa kuti kutenderera kwendege yepolarization kana ichipfuura nepakati pemagineti yakabvaChaizvoizvo, kubva pakubatana pakati pemunda wemagetsi wechiedza uye zvikwereti zvezvinhu.
El Basa idzva rinopokana kuti iyo magineti chikamu che electromagnetic field haina kungofamba: inokurudzira a mukati maginiti torque pakati, zvakafanana kune anogara ari kunze magnetic field, uye mugumisiro wacho hausi wesara pasi pemamwe mamiriro e spectral.
Methodology uye theoretical modhi
Chikwata ichi, chinotungamirwa naAmir Capua naBenjamin Assouline, vanoshandisa iyo Landau-Lifshitz-Gilbert equation kutsanangura simba rema electron spins mune magineti zvinhu zviri pasi pekuita kwemagnetic field yechiedza.
Kuumbwa kunoratidza sei Iyo oscillating magnetic component inoroora kune spins uye inoshandisa torque inoyerwaMukusimbisa kwavo, vanyori vakasarudza referensi crystal mumagneto-optics: the gallium-terbium garnet (TGG), yakashandiswa zvakanyanya kudzidza uye kugadzirisa maitiro eFaraday.
Quantitative mhedzisiro muTGG
Kushandisa iyo modhi kuTGG, iyo magineti mupiro wechiedza inotsanangura nezve imwe 17% yepolarization kutenderera mune inooneka spectrum uye inogona kukwira kusvika 70% mu infrared, magnitudes anomanikidza kuongororwa kweanojairwa kududzira.
Huremu hwemupiro wega wega hunoenderana ne wavelength uye iyo optical uye magineti zvimiro zvezvinhu, zvichikurudzira dhizaini chiyero chekugadzirisa magneto-optical zvishandiso mumabhandi akasiyana.
Zvinoreva optics, spintronics uye quantum tekinoroji muEurope
Mune yakashandiswa optics, kudzora nemaune kwe chiedza-induced magnetism Iyo yaizobvumira kugadziridzwa kwemaoptical isolators, Faraday modulators, uye ma sensors emunda ane mazano matsva akavakirwa pa spectral engineering.
Mune spintronics, kushandisa iyo magineti chikamu chedanda kutyaira iyo spin ruzivo kugadzirisa Inogona kufambisa ndangariro dzakanyanya kushanda uye Ultra-nekukurumidza switching zvirongwa pasina magetsi kubata.
Kune quantum tekinoroji, mwenje-magineti yekubatanidza inonongedza nzira dzekushandisa spin-based qubits, nekufarira kweEuropean ecosystems yakatarisana neiyo yakabatanidzwa photonics uye inopindirana kutonga kwemagineti nyika.
Chii chasara kusimbiswa
Kunyangwe humbowo hwakapihwa huri hwefungidziro, basa racho rinoratidza chirongwa chekuyedza chinonzwisisika: yakanyanya kucherekedza magneto-optical metrology, rigorous spectral calibration, uye kushandiswa kwe yakanyanya kugadzikana magetsi manyuko kuparadzanisa zvisina kujeka mupiro wemagineti kubva kune yemagetsi.
European photonics zvivakwa uye mayunivhesiti marabhoritari anogona kugadzirisa izvi kuyedza kusimbiswakuwedzera kuongororwa kune mamwe magineti-optical zvinhu, zvinosanganisira akabatanidzwa waveguides uye resonators.
Mibvunzo yakakosha yechidzidzo
Ndiani anosaina basa? Chikwata kubva ku Yunivhesiti yechiHebheru yeJerusarema, naAmir Capua naBenjamin Assouline vari kutungamira.
Rakabudiswa kupi? Mujenari yakavhurika yekuwana Mishumo yeSainziizvo zvinoita kuti kuongorora uye kubereka nemamwe mapoka.
Mashoko api akaongororwa? TGG crystal, ireferensi muzvidzidzo zveFaraday mhedzisiro nekuda kwayo high magneto-optical mhinduro.
Nei zvine basa? Nokuti inoratidza kuti chiedza, kunze kwekuita kwayo kwemagetsi, ine a yakananga magineti pesvedzero uye inogoneka pachinyorwa, ine chekuita nekugadzirwa kwemudziyo.
Chikumbiro chinowedzera runyoro rwekunyatso kunzwisiswa kwe Faraday effectInosanganisa basa remagineti echiedza nenhamba uye yakasimba theoretical chimiro, uye inovhura nzira inoshanda yekushandisa mupiro uyu mufotonic uye quantum mashandisiro anonyanya kufarira kuEuropean research uye machira emaindasitiri.
Ini ndiri anofarira tekinoroji akashandura zvaanofarira zve "geek" kuita basa. Ndapedza makore anopfuura gumi ehupenyu hwangu ndichishandisa tekinoroji yekucheka-kumucheto uye kutamba nemhando dzese dzezvirongwa kunze kwekuda kuziva. Iye zvino ndava nyanzvi mune zvekombiyuta uye mitambo yemavhidhiyo. Izvi zvinodaro nekuti kweanopfuura makore 10 ndanga ndichishanda kunyora kune akasiyana mawebhusaiti pane tekinoroji nemitambo yemavhidhiyo, ndichigadzira zvinyorwa zvinotsvaga kukupa ruzivo rwaunoda mumutauro unonzwisisika nemunhu wese.
Kana iwe uine chero mibvunzo, ruzivo rwangu rwunobva kune zvese zvine chekuita neWindows inoshanda sisitimu pamwe ne Android yenharembozha. Uye kuzvipira kwangu kuri kwauri, ndinogara ndakagadzirira kushandisa maminetsi mashoma uye kukubatsira kugadzirisa chero mibvunzo yaungave unayo munyika ino yeinternet.
