Generalized Slater-Pauling curve for transition-metal magnets

Abstract

An informative new way of plotting magnetization data for transition-metal alloys is described. The plot is used to distinguish a variety of generic alloy types including: 1) a large class for which the magnetization data fall near a common straight line, 2) magnetically strong and weak amorphous alloys, and 3) Co alloys with metalloids, such as Si and P, exhibit regular, easily interpreted behavior. Self-consistent spin-polarized energy-band calculations are used to explain the trends revealed by the plotting construction.
