Cele mai mici structuri magnetice de tip skyrmion (numite astfel \u00een onoarea fizicianului teoretician britanic Tony Skyrme, care a prezis aceast\u0103 structur\u0103 \u00een anii '60) promit s\u0103 devin\u0103 baza memoriei magnetice a viitorului. Aceste forma\u021biuni magnetice topologic stabile pot fi excitate \u00een pelicule magnetice \u0219i apoi citite starea lor. \u00cen acest proces, scrierea \u0219i citirea se fac folosind curen\u021bi de spin - prin transferul momentului de rota\u021bie al electronilor. Aceasta \u00eenseamn\u0103 c\u0103 scrierea \u0219i citirea se pot realiza cu curen\u021bi extrem de mici. De asemenea, suportul pentru vortexul magnetic nu necesit\u0103 alimentare constant\u0103, ceea ce duce la o memorie economic\u0103 \u0219i independent\u0103 energetic.<\/p>\n

Mai mult, recent, cercet\u0103torii britanici \u0219i americani au g\u0103sit o modalitate<\/a><\/noindex>, prin care se poate cre\u0219te densitatea \u00eenregistr\u0103rii de mai multe ori folosind skyrmioni f\u0103r\u0103 complexit\u0103\u021bi deosebite, cum ar fi reducerea diametrului structurilor vortex, ceea ce ar putea conduce la o realizare mai rapid\u0103 a g\u00e2ndirii \u0219tiin\u021bifice \u00een produse comerciale.<\/p>\n

\u00cen locul \u00eenregistr\u0103rii binare tradi\u021bionale, unde 1 \u0219i 0 ar fi un skyrmion sau absen\u021ba acestuia, cercet\u0103torii de la Universitatea Birmingham, Universitatea Bristol \u0219i Universitatea Colorado din Boulder au prezentat o structur\u0103 de v\u00e2rtej combinat\u0103 pe care au numit-o \u201esacul cu skyrmioni\u201d (skyrmion bag). Cu siguran\u021b\u0103, \u201esacul\u201d cu skyrmioni este mai bun dec\u00e2t un singur skyrmion. Num\u0103rul de skyrmioni din sac poate fi oric\u00e2t, ceea ce \u00eei va permite s\u0103 aib\u0103 mai multe valori dec\u00e2t 0 sau 1. Aceasta este o cale direct\u0103 spre cre\u0219terea densit\u0103\u021bii de \u00eenregistrare. \u00centr-o anumit\u0103 m\u0103sur\u0103, este comparabil\u0103 cu \u00eenregistrarea multi-nivel \u00een celulele de memorie NAND flash. Nu este nevoie s\u0103 ne amintim c\u00e2t de repede s-a extins pia\u021ba unit\u0103\u021bilor flash dup\u0103 \u00eenceputul produc\u021biei de mas\u0103 a memoriei NAND TLC, care \u00eenregistreaz\u0103 trei bi\u021bi \u00een fiecare celul\u0103.<\/p>\n

\"Skyrmioni<\/p>\n

Cercet\u0103torii din Anglia au prezentat crearea structurii \u201esacului cu skyrmioni\u201d sub form\u0103 de model abstract \u0219i au reprodus fenomenul \u00een cadrul unui program simulator. Colegii lor americani au reprodus fenomenul \u00een practic\u0103, de\u0219i pentru activarea structurilor de v\u00e2rtej au folosit cristale lichide, \u0219i nu structuri magnetice. Cristalele lichide, dup\u0103 cum se \u0219tie, sunt controlate de c\u00e2mpul magnetic, ceea ce permite utilizarea lor pentru experimente de simulare vizual\u0103 a fenomenelor magnetice.
