K\u00f5ige v\u00e4iksemad magnetilised vorteestruktuurid, mida nimetatakse skirmioonideks (nende nimi on saadud Briti teoreetiku Tony Skyrme'i j\u00e4rgi, kes ennustas selliste struktuuride olemasolu 1960. aastatel), lubavad saada tuleviku magnetilise m\u00e4lu aluseks. Need on topoloogiliselt stabiilsed magnetilised moodustised, mida saab aktiveerida magnetfooliumites ja seej\u00e4rel nende olekut lugeda. Samuti toimub kirjutamine ja lugemine spinni voolude abil - kasutades elektronide spinni p\u00f6\u00f6rlemise hetke \u00fclekannet. See t\u00e4hendab, et kirjutamine ja lugemine v\u00f5ivad toimuda \u00e4\u00e4rmiselt v\u00e4ikeste vooludega. Lisaks ei vaja magnetilise vortexi toetamine pidevat toiteallika \u00fchendamist, mis viib energias\u00f5ltumatute ja \u00f6konoomsete m\u00e4lu lahendusteni.<\/p>\n

\"Skirminoone<\/p>\n

Viimastel aastatel on teadlased Venemaal<\/a><\/noindex> ja v\u00e4lismaal<\/a><\/noindex> t\u00e4helepanelikult uurinud skirmioonide k\u00e4itumist ja mitte asjata usuvad nad, et need struktuurid aitavad oluliselt suurendada magnetkirjutuse tihedust. Veelgi enam, hiljuti avastasid Briti ja Ameerika teadlased viisi<\/a><\/noindex>, kuidas saab kergesti suurendada kirjutustiheduse, kasutades skirmioone ilma eriliste raskusteta, nagu n\u00e4iteks vorteestruktuuride diameetri v\u00e4hendamine, mis v\u00f5ib viia teaduslike ideede kiirema elluviimiseni kommertstoode.<\/p>\n

\n<\/center><\/p>\n

Birmingham \u00fclikooli, Bristoli \u00fclikooli ja Colorado \u00fclikooli Boulderis teadlased esitlesid kombineeritud keerise struktuuri, mida nad nimetasid «sk\u00fcirmioni kott» (skyrmion bag). Kahtlemata on «kott» k\u00fcirmionitest parem kui \u00fcksik k\u00fcirmion. Kotis olevate k\u00fcirmionide arv v\u00f5ib olla mis tahes, mis v\u00f5imaldab sellele anda rohkem v\u00e4\u00e4rtusi kui 0 v\u00f5i 1. See on otse tee salvestustiheduse suurendamiseks. Teatud m\u00e4\u00e4ral on see sarnane mitme taseme salvestamisele NAND-fla\u0161im\u00e4lus. Pole vaja eraldi meenutada, kui kiiresti hakati p\u00e4rast NAND TLC m\u00e4lu massiivset tootmist laienema fla\u0161im\u00e4lu turg, kus igasse m\u00e4llu kirjutatakse kolm bitti.<\/p>\n

\"Skirminoone<\/p>\n

Teadlased Inglismaal esitlesid «sk\u00fcirmioni kotti» abstraktsel mudelina ja taasesitasid n\u00e4htuse simulaatorprogrammis. Nende Ameerika kolleegid taasesitasid n\u00e4htuse praktikas, kuigi nad kasutasid keerise struktuuride aktiveerimiseks vedelkristalle, mitte magnetilisi struktuure. Vedelkristallide, nagu on teada, juhib magnetv\u00e4li, mis v\u00f5imaldab neid kasutada esituseksperimentides magnetiliste n\u00e4htuste visualiseerimiseks. Ootame katsete \u00fcleviimist magnetkiledele.<\/p>\n
