Zing'onozing'ono maginito vortex nyumba, skyrmions (wotchedwa British theoretical physicist Tony Skyrme, amene ananeneratu za dongosolo limeneli mu 60s wa zaka zapitazi) kulonjeza kukhala maziko a kukumbukira maginito za m'tsogolo. Awa ndi maginito okhazikika a maginito omwe amatha kukondwera ndi mafilimu a maginito ndiyeno dziko lawo likhoza kuwerengedwa. Pamenepa, kulemba ndi kuwerenga kumachitika pogwiritsa ntchito mafunde ozungulira - posamutsa mphamvu ya angular ya electron spin. Izi zikutanthauza kuti kulemba ndi kuwerenga kumatha kuchitidwa ndi mafunde otsika kwambiri. Komanso, kuthandizira maginito vortex sikufuna mphamvu yamagetsi yokhazikika, yomwe imatsogolera ku kukumbukira kosasunthika kwachuma.
M'zaka zingapo zapitazi, asayansi apanga ndi akuphunzira mozama momwe ma skyrmions amachitira ndipo, osati mopanda nzeru, amakhulupirira kuti mapangidwewa athandizira kukulitsa kachulukidwe ka maginito kujambula. Komanso, posachedwa asayansi aku Britain ndi America , momwe zingathekere kuonjezera kwambiri kachulukidwe kujambula pogwiritsa ntchito ma skyrmions popanda zovuta zina mwa njira yochepetsera m'mimba mwake ya mapangidwe a vortex, zomwe zingayambitse kukhazikitsidwa kwachangu kwa malingaliro asayansi kukhala malonda.
M'malo mwazolemba zamabina, pomwe 1 ndi 0 ingakhale skyrmion kapena ayi, asayansi ochokera ku Yunivesite ya Birmingham, Bristol ndi University of Colorado Boulder adapereka mawonekedwe ophatikizika a vortex omwe amawatcha "skyrmion bag." Mosakayikira, "chikwama" cha skyrmions ndi chabwino kuposa skyrmion imodzi. Chiwerengero cha ma skyrmions mu thumba chikhoza kukhala chilichonse, chomwe chidzalola kuti chigawidwe chamtengo wapatali kuposa 0 kapena 1. Iyi ndi njira yolunjika yowonjezeretsa kujambula. Pamlingo wina, izi zikufanana ndi kulemba kwamitundu yambiri ndi cell ya NAND flash. Palibe chifukwa chokumbutsanso momwe msika wamagetsi wamagetsi unayambira kukulira pambuyo poyambira kupanga misala ya kukumbukira kwa NAND TLC ndikulemba ma bits atatu pa selo.
Asayansi ochokera ku England adawonetsa kupanga mapangidwe a "chikwama cha skyrmions" mu mawonekedwe azithunzi ndipo adatulutsanso chodabwitsachi mu pulogalamu yoyeserera. Anzawo aku America adapanganso chodabwitsachi, ngakhale adagwiritsa ntchito makhiristo amadzimadzi m'malo mogwiritsa ntchito maginito poyambitsa ma vortex. Makhiristo amadzimadzi amadziwika kuti amawongoleredwa ndi mphamvu ya maginito, yomwe imawalola kuti agwiritsidwe ntchito poyesera mokhazikika kuti awonetse zochitika zamaginito. Tikudikirira kuti zoyeserera zisamutsidwe ku mafilimu a maginito.
