Time-resolved SANS study of slow dynamics in the spin-glass alloy Fe0.70Al0.30

In order to probe the microscopic mechanism of slow dynamics in spin-glass materials, a time-resolved small angle neutron scattering (SANS) experiment has been made. Time-resolved SANS patterns from a concentrated spin-glass alloy Fe0.70Al0.30 have been taken up to 20 h under various temperature and...

description In order to probe the microscopic mechanism of slow dynamics in spin-glass materials, a time-resolved small angle neutron scattering (SANS) experiment has been made. Time-resolved SANS patterns from a concentrated spin-glass alloy Fe0.70Al0.30 have been taken up to 20 h under various temperature and magnetic field with a typical time window of 10-30 min. We discuss the temperature and magnetic field dependence of the time evolution of the scattering pattern based on a magnetic cluster model.
