<p>Metallic glasses having high permeability, low magnetostriction, low coercivity low ac core loss, low exciting power and high thermal stability are disclosed. The metallic glasses consist essentially of about 66 to 82 atom percent iron, from 1 to about 8 atom percent of said iron being, optionally replaced with nickel and or cobalt, about 1 to 6 atom percent of at least one element selected from the group consisting of chromium, molybdenum, tungsten, vanadium, niobium, tantalum, titanium, zirconium and hafnium, about 17 to 28 atom percent of boron, 0.5 to 6 atom percent of said boron being, optionally, replaced with silicon and up to 2 atom percent of boron being, optionally, replaced with carbon, plus incidental impurities. Such metallic glasses are especially suited for use in tape heads, relay cores, transformers and the like.</p> |
