Abstract
Continuously cast metallic glasses [METGLASR (trademark of the Allied Chemical Corporation) alloys] based on the transition metals (TM) iron,cobalt, and nickel can now be synthesized containing boron as the only metalloid. The different electron‐donor effects of boron and phosphorus are clearly seen for the first time; each atom of these metalloids gives ∼1.6 and 2.4 electrons, respectively, to the TM d bands. Extrapolation of the available magnetic moment data suggests a nonzero moment on nickel in (TM)80B20 glasses. The boron‐containing metallic glasses generally show higher Curie temperatures and room‐temperature saturation magnetizations than mixed‐metalloid glassy alloys of the same TM content.Keywords
