The physical properties of many of the rare-earth intermetallic compounds have been collected together. They are discussed in terms of the role that the magnetic exchange and crystal field interactions play in determining these properties. It is pointed out that in this vast number of materials there is an ideal chance of establishing which of several second-order terms are effective in determining structural stability.

Intermetallic rare-earth compounds.

Structure and stability of Laves phases. Part I. Critical assessment of factors controlling Laves phase stability

Topologically close-packed structures of transition metal alloys

Structure and stability of Laves phases part II—structure type variations in binary and ternary systems

A recently developed cell theory for multicomponent solid solutions is applied to the study of substitutionally ordered binary hard sphere solid solutions. Solid phase thermodynamic properties and solid–fluid phase diagrams have been determined for a range of particle size ratios. The theoretical predictions agree well with available Monte Carlo simulation results. From the phase diagrams we draw some conclusions about the domains of stability of some simple compounds such as AB, AB2, and AB13 in terms of the size ratio, density, and overall composition of the mixture.
