Taking these results into account it arises that the presence of Al admixtures in the crystal lattice of transition alloys causes the inflation of the unit cell, the decrease of the magnetic moment of the transition atoms, the decrease of the Curie temperature and the increase of the resistivity. KEYWORDS A. alloys, A. magnetic materials, D. crystal structure, D. electrical properties, D. magnetic properties INTRODUCTION The influence of the Al admixtures on the electronic and crystal structure of the 3d transition alloys has not been fully studied to date, although these alloys are of prime interest in solid state physics and have been widely used in industry since the beginning of the century (1). This paper constitutes part of a research program which, on the one hand, aims at the systematic study of the influence of the Al admixtures on the crystal and electronic structure of the 3d transition alloys and, on the other hand, aims at the publication of the experimental results which will complete the international bibliography concerning the behavior of these alloys. The program is to be fulfilled within the framework of the bilateral scientific cooperation of Greece and Germany and conducted by the Aristotle University of Thessaloniki, Greece and the Technische Braunschweig, Germany. zyxwvutsrqponmlkjihgfedcba 1471
