Iyo diki magineti vortex zvimiro, skyrmions (yakatumidzwa zita reBritish theoretical physicist Tony Skyrme, uyo akafanotaura chimiro ichi mu60s yezana ramakore rapfuura) anovimbisa kuve hwaro hwemagineti memory yeramangwana. Aya ndiwo maumbirwo akadzikama magineti epamusoro anogona kunakidzwa mumafirimu emagineti uyezve mamiriro avo anogona kuverengwa. Muchiitiko ichi, kunyora uye kuverenga kunoitika uchishandisa spin currents - nekufambisa nhanho yeangular ye electron spin. Izvi zvinoreva kuti kunyora uye kuverenga kunogona kuitwa nemhepo yakaderera zvakanyanya. Zvakare, kutsigira magineti vortex hakudi kuti irambe iine simba rekupa, izvo zvinotungamira kune yehupfumi isiri-inotenderera yekurangarira.
Mumakore mashoma apfuura, masayendisiti mune uye vari kunyatsodzidza maitiro e skyrmions uye, kwete zvisina musoro, vanotenda kuti izvi zvimiro zvichabatsira zvakanyanya kuwedzera magineti yekurekodha density. Uyezve, munguva pfupi yapfuura masayendisiti eBritain neAmerica , zvinogoneka sei kuwedzera zvakanyanya kurekodha density uchishandisa skyrmions pasina kuomerwa kwakasiyana nenzira yekudzikisa dhayamita yezvimiro zvevortex, izvo zvinogona kutungamira mukududzirwa nekukurumidza kwemazano esainzi kuita chigadzirwa chekutengesa.
Panzvimbo pechinyakare mabhinari notation, apo 1 na 0 vangave skyrmion kana pasina skyrmion, masayendisiti kubva kuYunivhesiti yeBirmingham, Bristol neYunivhesiti yeColorado Boulder vakapa yakasanganiswa vortex chimiro chavakadaidza kuti "skyrmion bag." Pasina mubvunzo, "bhegi" rekudenga riri nani pane imwe skyrmion. Nhamba ye skyrmions mubhegi inogona kuva chero ipi zvayo, iyo ichakubvumira kuti uipe iyo yakawanda inokosha kupfuura 0 kana 1. Iyi inzira yakananga yekuwedzera kurekodha density. Kusvika kumwero wakati, izvi zvinofananidzwa nekunyora-matanho akawanda kune NAND flash cell. Iko hakuna chikonzero chekuyeuchidza zvakare kuti nekukurumidza sei musika weflash drive wakatanga kukura mushure mekutanga kugadzirwa kwakawanda kweNAND TLC memory nekunyora matatu mabheti pasero.
Masayendisiti kubva kuEngland akapa kusikwa kwechimiro che "bhegi rekudenga" nenzira yeabstract model uye akadzokorora chiitiko muchirongwa chesimulator. Vamwe vavo vekuAmerica vakaburitsa chiitiko ichi mukuita, kunyangwe vakashandisa makristasi emvura pane magineti zvimiro kuvhura vortex zvimiro. Makristasi emvura anozivikanwa kuti anodzorwa negineti, ayo anoatendera kuti ashandiswe pakuita ongororo yekuona magineti zviitiko. Isu takamirira kuti zviedzo zviendeswe kune magineti mafirimu.
