Abstract
Studies of the changes in magnetic properties of PtCo and PtFe consequent on replacing part or whole of the platinum by palladium, rhodium, iridium and ruthenium, and on preparative methods and heat treatments for these alloys, have shown that the pseudobinary alloys do not appear to offer improvements in magnetic properties. By careful heat treatment of PtCo, made by sintering and working or by vacuum melting, energy products of 9.5 and 10.0 × 106Gs-Oe, combined with coercive forces of 5.0 and 4.5 × 103Oe respectively, can be obtained.
