Interplays of mu SR, Susceptibility, and Neutron Studies on Dilute-Alloy Spin Glasses

摘要

Static spin polarization of Fe moments in a spin glass AuFe, determined by zero-field mu SR, is compared to an ac-susceptibility measurement below the cusp temperature T/sub g/, and a rather uniform amplitude of the static polarization is pointed out for frozen spins. Completely random orientation of frozen spins is revealed by neutron scattering in a dilute 1% CuMn, and an importance of comparing results of these different methods is demonstrated.
