Abstract
Experimental information on the electronic properties of ordered ZrRh alloys is presented through low temperature specific heat and magnetic susceptibility measurements. In general, a low density of states at the Fermi level is deduced and this is explained by a split band regime consistent with the known DOS calculatios for the type of ordered structures considered. The existence of a split band is considered as typical of stable ordered structures. Zr 2Rh, which is a superconductor with T c = 11.2 K possesses a very high electronic specific heat coefficient. It is suggested that this high λ value is associated with a decrease of stability of the ordered structure and an increased ability to form amorphous alloys when the concentration of Zr increases.
