説明

<jats:p>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.</jats:p>
