摘要：

Muon spin relaxation measurements of RE8Mg42Zn50 (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. (C) 1998 Elsevier Science B.V.
