AMORPHOUS ALLOY FOR MAGNETIC HEAD AND MAGNETIC HEAD WITH AN AMORPHOUS ALLOY

An amorphous alloy for a magnetic head has a composition which may be represented as Co100-T-X-Y-ZNiTHfXBySiZ, where T, X, Y and Z satisfy the conditions of 0.75?T?14, 6?X?15, 3?Y?8, 0?Z?0.01, 3?Y+Z?13, and 11?X+Y+Z?25. Such an amorphous alloy has a high crystallization temperature, said temperature...

Beschreibung
Zusammenfassung:	An amorphous alloy for a magnetic head has a composition which may be represented as Co100-T-X-Y-ZNiTHfXBySiZ, where T, X, Y and Z satisfy the conditions of 0.75?T?14, 6?X?15, 3?Y?8, 0?Z?0.01, 3?Y+Z?13, and 11?X+Y+Z?25. Such an amorphous alloy has a high crystallization temperature, said temperature being higher than 500.degree.C, and does not lower the effective magnetic permeability, even if gradual cooling is performed after heat treatment. A magnetic head having a core consisting of such an amorphous alloy is not deteriorated in its magnetic properties, even if the head is made by glass bonding.
