Description

Zero-field muon spin relaxation (μSR) in non-Fermi liquid Ce0.2La0.8RhIn5 reveals disordered spin freezing with a sharp transition at 0.16K. The frozen moment at T=0 is estimated as ∼0.13μB/Ce, an order of magnitude smaller than found from thermodynamic data at higher fields and temperatures. Longitudinal-field μSR exhibits no dynamic relaxation at any temperature, showing that the spin freezing is not accompanied by the slow spin fluctuations found in spin glasses above the glass temperature and in other disordered non-Fermi liquid systems
