On nature of the excess heat capacity in icosahedral quasicrystals

Experimental evidence is presented which indicates that the total heat capacity in the Al 63 Cu 25 Fe 12 icosahedral phase contains a contribution associated with inconstancy of the charge carrier concentration. The contribution has an oscillating temperature dependence and is supposedly traceable t...

Description
Summary:Experimental evidence is presented which indicates that the total heat capacity in the Al 63 Cu 25 Fe 12 icosahedral phase contains a contribution associated with inconstancy of the charge carrier concentration. The contribution has an oscillating temperature dependence and is supposedly traceable to two Schottky-like heat anomalies.
