Magnetic moments in solids become useful and interesting due to the interatomic exchange that causes them to align. Developments in calculations of the electronic structure of solids have led to the ability to predictively compute these interactions in many materials. This review describes the development of these calculations and their application in describing the behavior of materials including technologically important hard and soft magnetic materials, novel two-dimensional magnets, elemental solids, alloys, antiferromagnets, noncollinear magnets, and magnetic molecules containing hundreds of atoms.
