| Popis: |
We have used neutron scattering and muon spin relaxation (muSR) to investigate the structural and magnetic properties of the beta-phase of elemental manganese doped with dilute amounts of indium. beta-Mn is an example of a topologically frustrated antiferromagnetically correlated metal - but which remains paramagnetic at all temperatures. The addition of In to beta-Mn results in a vast volume expansion of the lattice, and would therefore be expected to have a major effect on the stability and localization of the Mn moment - as observed in, for example, Ru and Al doped beta-Mn alloys. We find that In doping in beta-Mn results in a short-range ordered spin-glass like ground state, similar to that of Al-doped beta-Mn but with residual low frequency spin fluctuations. This is in contrast to Ru doping which results in the stabilization of a long-range ordered Mn moment |
