Magneto-Optic terbium-iron-cobalt based alloys. Produced to a high degree of compositional control and with very low levels of critical impurities such as oxygen. Alloying Additions: Gadolinium may be used as a substitute for terbium; tantalum and/or chromium are common additions to Tb-Fe-Co systems. Form: Routinely supplied in the form of powder, milled to a specific size requirement. |
