Popis:	Muon spin relaxation measurements of RE 8 Mg 42 Zn 50 (RE = Gd, Tb) quasicrystals have revealed slower spin dynamics and more prompt spin freezing for Tb than Gd, due to “crystalline electric field” splitting in low rare-earth site symmetry. Inhomogeneous spin freezing leads to a low-temperature state with local field distribution characteristic of a concentrated disordered magnet.
