| 摘要 |
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 DEG 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.
