ELECTRONIC-STRUCTURE OF 3D TRANSITION-METAL SOLUTES IN LIQUID ALUMINUM

The changes in the electrical resistivity, the thermoelectric power an d the magnetic susceptibility of liquid Al due to the addition of smal l amounts of Ti, V, Cr, Mn, Fe, Co and Ni (1 at.%) are discussed. The variation of the residual resistivity across the series exhibits a cha racteristic two-peak shape in contrast to the single peak of the solid state. The analysis of the position and the width of the virtual boun d d states and the pronounced increase of the magnetic susceptibility point to a magnetically split band structure in the middle of the seri es. Impurities of Cr and Mn are indicated to be magnetic. V and Fe are presumably on the borderline, whereas Ti, Co and Ni are definitely no nmagnetic if dissolved in liquid Al.
