Magnetisches Material und Herstellungsverfahren

摘要

A magnetic material consisting essentially of Al and 10 to 50 at.% of at least one capable of alloying with Al to form quasicrystals (for example, 5 to 25 at.% of at least one member selected between Cu and Pd and 5 to 35 at.% of Mn) and up to 25 at.% of at least one element having a smaller atomic radius than those of the above elements (for example, B). The magnetic material is produced by adding, to a mixture consisting of Al and at least one element capable of alloying with Al to form quasicrystals and including at least one transition metal, at least one element having a smaller atomic radius than those of Al and the above elements to dissolve the element having a smaller atomic radius in a solid solution form in a quasicrystalline phase. The thus obtained magnetic crystal is useful in various applications, such as magnetic recording heads, and a process for producing the same.
