Covers a broad range of topics on the crystal chemistry, thin-film and crystal growth, and various physical properties of rare-earth borides, including detailed reviews of their structural and thermodynamic properties, electronic properties in the bulk and at the surface, and magnetic behavior at low temperatures from the perspective of both theory and experiment Includes a comprehensive review of the crystal-growth methods and their influence on the quality of single-crystalline samples across different structural families of rare-earth borides Encompasses comprehensive reviews of the lattice and electron dynamical properties from the perspective of Raman scattering, inelastic neutron scattering, and x-ray spectroscopy. In particular, a multifaceted analysis of the low-temperature magnetic dynamics associated with the multipolar ordering phenomena is highlighted Contains two chapters on the theory of multipolar excitations in rare-earth borides, authored by the leading experts in the physics of f-electron Kondo systems Features a contribution by Priscila F. S. Rosa and Zachary Fisk about the electronic properties of the Kondo insulator SmB6 that received a lot of attention in recent years due to its intensely debated topological electronic properties
