Abstract
<p>Recent developments of the theory of crystalline electric field (CEF) and magnetism in the rare-earth based quasicrystals and approximant crystals are overviewed. Magnetic anisotropy arising from the CEF plays a key role in realizing unique magnetic states characterized by the topological charge on the icosahedron. Topological Hall effect is shown to appear under magnetic field accompanied by metamagnetic as well as topological transition in the Tb-based approximants. Ferromagnetic long-range orders have been discovered in the Tb-based quasicrystals.</p>
