Carbon nanotubes have found another application. A few days ago, an article was published in Nature Scientific Reports that discusses for the first time the possibility of using multi-walled carbon nanotubes (MWCNT) in magnetic recording on hard drives. These are diverse complex CNT structures in the form of \"matryoshka dolls,\" \"scrolls,\" and other configurations. The task in all cases boils down to one - to fill each complex carbon nanotube with magnetic nanoparticles. Individual magnetic nanoparticles will not yield a data recording effect. Magnetization can only be altered with the entire tube, but this will still be denser than recording magnetically. dom\u00e6ne<\/a> p\u00e5 en almindelig HDD-magnetplade. M\u00e6gtigere.<\/p>\n

\"Magnetiske<\/p>\n

Forskningen om magnetisk datalagring p\u00e5 MWCNT er udf\u00f8rt af forskere fra Universitetet i Alaska (Fairbanks) og flere andre forskningsinstitutioner i USA og Tjekkiet<\/a>One of the project leaders is Czech scientist Gunther Kletetschka. The specialist notes that current methods for increasing the recording density on HDDs no longer meet the speed of data growth. To control the growth of data, it is necessary for the storage density on hard drives to increase by 40% each year, while in recent years it has been growing by 10-15% annually. Recording using carbon magnetic tubes may be the answer to the challenges of the information age, but substantial research work still lies ahead.<\/p>\n

Kernen i \u00e5bningen er, at kulstofnanor\u00f8r med magnetiske nanopartikler indeni blev udsat for et elektromagnetisk felt med forskellige amplituder og frekvenser. Fremstillingen af de fyldte nanopartikler i kulstofr\u00f8rene blev for \u00f8vrigt udf\u00f8rt ved hj\u00e6lp af deposition i gasform - intet nyt. Ved p\u00e5f\u00f8ring af et magnetfelt med en frekvens p\u00e5 op til 10 kHz skete der ikke noget (overfladeeffekten af ledningsevnen af kulstofnanor\u00f8rene havde indflydelse), men med en stigning i frekvensen over 10 kHz og et fald i feltets amplitude opstod der en magnetiseringseffekt af kulstofnanor\u00f8ret med de magnetiske nanopartikler. Forskere mener, at det eksterne felt svarede til det magnetiske felt af de enkelte partikler, hvilket gjorde det muligt at give nanor\u00f8ret en stabil magnetisering i en given retning.<\/p>\n

\"Magnetiske<\/p>\n

Forskere har endnu ikke forslag til, hvordan man kan skabe billederings- og l\u00e6semekanismer til at lagre data p\u00e5 et array af kulstofnanor\u00f8r, men de lover at arbejde h\u00e5rdt p\u00e5 dette omr\u00e5de, da m\u00e6ngden af data over tid ikke vil blive mindre.<\/p>\n
