Abstract
The field and temperature dependence of the magnetisation is studied in a stable Al-Cu-Fe icosahedral phase, in the temperature region between 77 and 1050 K and in magnetic fields up to 18 kOe. The sample shows a good quality of structural perfection in X-ray diffraction and electron microscope observations as compared with known icosahedral phases. The magnetic susceptibility shows an increase from -1.5*10-7 to 4.5*10-7 EMU g-1 with a rise in temperature from 150 to 1050 K, which has not been observed icosahedral phases studied to date.Keywords
