Vesainzi vatora danho rekugadzira michina ine simba inobatamagnetic kuchaja nekugadzira yekutanga-dimensional replica yechinhu chinonzi spin-ice.
Spin ice zvinhu zvakanyanya kujairika sezvo vaine izvo zvinonzi hurema hunoita sedanda rimwe remagineti.
Aya magineti edanda rimwe chete, anozivikanwawo semagineti monopoles, haapo mune zvakasikwa; kana magineti ese akachekwa kuita maviri anogara achigadzira magineti matsva ane pole yekuchamhembe nekumaodzanyemba.
Kwemakumi emakore masayendisiti ave achitarisa kure uye kure kuti awane umboo hwezvinoitika zvogamagnetic monopoles mune tariro yekuzopedzisira yaunganidza masimba akakosha echisikigo mune inonzi dzidziso yezvese, kuisa yese yefizikisi pasi pedenga rimwechete.
Zvakadaro, mumakore achangopfuura nyanzvi dzefizikisi dzakakwanisa kugadzira shanduro dzemagineti monopole kuburikidza nekugadzira maviri-dimensional spin-ice zvinhu.
Kusvika iye zvino zviumbwa izvi zvakabudirira kuratidza magnetic monopole, asi hazvibviri kuwana fizikisi imwechete kana zvinhu zvakavharirwa kune imwe ndege. Hongu, ndiyo chaiyo-dimensional geometry ye spin-ice lattice ndiyo kiyi yekugona kwayo kusajairika kugadzira zvimiro zvidiki zvinotevedzera.magneticmonopoles.
Muchidzidzo chitsva chakaburitswa nhasi muNature Communications, timu inotungamirwa nemasayendisiti kuCardiff University yakagadzira yekutanga zvachose 3D replica ye spin-aizi zvinhu vachishandisa yakaomesesa mhando ye3D kudhinda uye kugadzirisa.
Chikwata ichi chinoti tekinoroji yekudhinda ye3D yakavatendera kuti vagadzirise geometry yeartificial spin-aizi, zvichireva kuti vanogona kudzora nzira iyo magineti monopoles anogadzirwa uye kufamba-famba mumasisitimu.
Kukwanisa kushandura magineti ediki monopole mu 3D kunogona kuvhura huwandu hwese hwezvishandiso zvavanoti, kubva pakuchengetedzwa kwekombuta kusvika pakugadzira 3D computing network inoteedzera chimiro cheneural chehuropi hwemunhu.
"Kwemakore anopfuura 10 masayendisiti ave achigadzira uye achidzidza artificial spin-ice mumativi maviri. Nokuwedzera masisitimu akadaro kusvika kumatatu-dimensions tinowana mufananidzo wakanyatsojeka we spin-ice monopole physics uye tinokwanisa kudzidza kushanda kwepasi," akadaro munyori anotungamirira Dr. Sam Ladak kubva kuCardiff University's School of Physics and Astronomy.
"Aka ndekekutanga kuti chero munhu akwanise kugadzira chaiyo 3D replica ye spin-aizi, nedhizaini, pane nanoscale."
Iyo artificial spin-aizi yakagadzirwa ichishandisa state-of-the-art 3D nanofabrication matekiniki umo ma nanowires akaturikidzana muzvikamu zvina mune retice chimiro, iyo pachayo yakayera isingasviki hupamhi hwebvudzi remunhu.
Yakakosha mhando yemicroscopy inozivikanwa semagineti simba microscopy, iyo inonzwa kune magineti, yakazoshandiswa kufungidzira magineti machaji aripo pachishandiso, ichibvumira timu kuti itarise mafambiro eiyo-pole-pole magineti kuyambuka 3D chimiro.
"Basa redu rakakosha sezvo richiratidza kuti nanoscale 3D printing technologies inogona kushandiswa kutevedzera zvinhu zvinowanzogadzirwa kuburikidza nekemesitiri," akaenderera mberi Dr. Ladak.
"Pakupedzisira, basa iri rinogona kupa nzira yekugadzira inoveli magineti metamaterials, uko zvinhu zvemukati zvinogadziriswa nekudzora iyo 3D geometry yelatisi yekugadzira.
"Magineti ekuchengetera zvigadziriso, senge hard disk drive kana magineti random access memory device, ndiyo imwe nzvimbo inogona kukanganiswa zvikuru nekubudirira uku. Sezvo midziyo iripo ichishandisa maviri chete kubva pamativi matatu aripo, izvi zvinomisa huwandu hweruzivo rwunogona kuchengetwa. Sezvo mamonopoles achigona kufambiswa kutenderedza 3D lattice uchishandisa magineti zvinokwanisika kugadzira chaiyo inoenderana nemagineti yekuchengetera 3D."
