μSR investigations of the spin glass transition in [formula omitted]Mn

The zero field muon spin depolarization measurements on Cu Mn single crystals ( c < 1 at% Mn) show that the spin glass freezing process above T f is inhomogeneous in space. The measured depolarization functions indicate the coexistence of regions of fast Mn-spin fluctuations (correlation times ⪡...

Description
Summary:The zero field muon spin depolarization measurements on Cu Mn single crystals ( c < 1 at% Mn) show that the spin glass freezing process above T f is inhomogeneous in space. The measured depolarization functions indicate the coexistence of regions of fast Mn-spin fluctuations (correlation times ⪡ 10 −9 s) with regions of spin glass order (distribution of correlation times between 10 −9 and 10 −6 s).
