Abstract
Recently, we introduced the ‘‘generalized Slater–Pauling’’ construction, in which the magnetization of most transition‐metal alloys fall near a universal and easily interpreted straight line. The construction is based on the idea that, in transition‐metal alloys, the solute d states lies either close (in energy) to the host d states, and join them in forming a ‘‘common band,’’ or they lie well above the host d states, forming a ‘‘split‐band’’ configuration. While most alloys are either split‐ or common‐band in character, we focus here on the exceptions, those that exhibit the transition from split‐ to common‐band behavior. These include the alloy series Ru‐Rh‐Pd and Os‐Ir‐Pt as solutes in ferromagnetic Co and Ni.
