摘要： An amorphous alloy for a magnetic head has a composition which may be represented as or where T, T', X, Y and Z satisfy the conditions of 0.75 ≤T≤14, 0.2≤T'≤1.5, 6≤X≤15, 3≤Y≤8 and 0≤Z≤0.01. Such an amorphous alloy has a high crystallization temperature, said temperature being higher than 500°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.
