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.
"Kweanopfuura makore gumi masayendisiti anga achigadzira uye achidzidza artificial spin-ice mumativi maviri.Nekuwedzera masisitimu akadaro kusvika kumativi matatu tinowana kumiririrwa kwakanyatso kujeka kwe spin-ice monopole physics uye tinokwanisa kudzidza kukanganiswa kwenzvimbo,” 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 zvishandiso, senge hard disk drive kana magineti isina kujairika yekuwana memory zvishandiso, imwe nzvimbo inogona kukanganiswa zvakanyanya nekubudirira uku.Sezvo zvigadziriso zvazvino zvinoshandisa zviviri chete kubva pazviyero zvitatu zviripo, izvi zvinomisa huwandu hweruzivo runogona kuchengetwa.Sezvo mamonopoles achigona kufambiswa kutenderedza 3D lattice uchishandisa simba remagineti zvinogoneka kugadzira chaiyo 3D yekuchengetedza mudziyo unoenderana nemagineti kuchaji.
