Abstract

Firele magnetice, amorfe şi nanocristaline, acoperite cu sticlă, conform invenţiei, sunt formate dintr-un miez metalic, amorf sau nanocristalin, cu diametre de ordinul micronilor, şi un înveliş de sticlă cu grosimi de acelaşi ordin de mărime, cu compoziţii ale miezului metalic pe bază de metal de tranziţie-metaloid şi adaosuri din alte metale. Firele au magnetizare la saturaţie medie sau ridicată, magnetostricţiune pozitivă, negativă sau aproape nulă şi valori ale câmpului coercitiv şi ale permeabilităţii magnetice, în funcţie de aplicaţiile dorite. Firele magnetice, amorfe şi nanocristaline, acoperite cu sticlă, se utilizează în electronică şi electrotehnică, la realizarea de senzori, traductoare, inductanţe, transformatoare, ecrane magnetice, dispozitive ce funcţionează pe baza corelării proprietăţilor magnetice ale miezului metalic şi proprietăţilor optice ale învelişului de sticlă. Procedeul conform invenţiei constă în topirea aliajului metalic, aflat într-un tub de sticlă, până la înmuierea acesteia, şi tragerea firului metalic împreună cu învelişul de sticlă.
