Heat capacities of dilute alloys of Fe in Cu below 1°K

The heat capacities of five alloys containing between 0.0081 and 0.27 at.% Fe in Cu have been measured between 0.06 and 1°K. The concentration dependence shows that Fe-Fe interactions are important, even in the most dilute alloy, at the lowest temperature, and suggests that the low-temperature heat...

Description
Summary:The heat capacities of five alloys containing between 0.0081 and 0.27 at.% Fe in Cu have been measured between 0.06 and 1°K. The concentration dependence shows that Fe-Fe interactions are important, even in the most dilute alloy, at the lowest temperature, and suggests that the low-temperature heat capacity characteristic of the spin-compensated state is proportional to temperature. Die Wärmekapazitätswerte von fünf 0,0081 bis 0,27 Atomprozent Fe in Cu enthaltenden Legierungen wurden von 0,06 bis 1°K gemessen. Die Konzentrationsabhängigkeit beweist, daβ Fe-Fe Wechselwirkungen sogar in äuβerst verdünnter Legierung bei niedrigster Temperatur bedeutend sind und man kann annehmen, daβ sich deshalb der Kennwert der Wärmekapazität bei niedriger Temperatur im spinkompensierten Zustand wärmeproportional verhält.
