Noemetallic Nature of the Interrelation of Thermal, Magnetic, and Electrical Properties In Icosahedral Quaskrystals at High Temperatures

摘要

In the icosahedral phase of Al-Cu-Fe alloys in the temperature range above 300 K there has been found an interrelation between the heat capacity, magnetic susceptibility, and conductivity not characteristic of typical metals. It is supposed that these phases are systems whose properties at finite temperatures are predominantly determined by excited electrons rather than by electrons with a Fermi energy E_F.
