Magnetic Field Dependence of the Specific Heat of Dilute Pd–Co, Pt–Co, and Pd–Mn Alloys

Abstract

The specific heat of dilute alloys of the type palladium‐cobalt has been measured in the temperature range from 1.2 to 30 K in external magnetic fields up to 30 kOe. Due to a high accuracy detailed results have been obtained. The excess specific heat appears to be strongly affected by magnetic fields. A comparison between palladium and platinum alloys reflects the smaller exchange enhancement in platinum. Preliminary results on dilute alloys of manganese in palladium show a striking difference between this element and cobalt and iron, when dissolved in palladium.
