Abstract

Przedmiotem wynalazku jest sposób wytwarzania nanodrutów magnetycznych, przeznaczonych w szczególnosci do wytwarzania nosników pamieci komputerowych. Sposób polega na tym, ze ferromagnetyczny surowiec rozdrobniony do czastek nanometrycznych umieszcza sie w poblizu zródla pola magnetycznego i poddaje dzialaniu niejednorodnego pola magnetycznego, które wytwarza sile magnetostatyczna opisana wzorem (A), gdzie: mx, my, mz sa wartosciami skladowymi wektora momentu magnetycznego czastek nanometrycznych, a Bx, By, Bz, to wartosci skladowych wektora indukcji pola magnetycznego, nastepnie pod wplywem tej sily na podlozu wykonanym z materialu niemagnetycznego, czastki nanometryczne koncentruja sie w miejscach o najwiekszych gradientach indukcji pola tworzac wysepki, które rozrastaja sie anizotropowo wzdluz linii sil pola magnetycznego i tworza nanodruty.
