Evolution of the spin fluctuations and spin dynamics in the inverse magnetocaloric effect compound Mn5Si3
Mn5Si3 shows the inverse magnetocaloric effect (MCE), the cooling by adiabatic magnetization. This effect is opposite to the more common direct MCE, the cooling by adiabatic demagnetization. In previous inelastic neutron scattering experiments we could show that among the two stable antiferromagnetic phases the high temperature one (AF2) shows an unusual magnetic excitation spectrum with coexisting propagative spin waves and diffuse spin fluctuations. Moreover, we could associate the inverse magnetocaloric effect with field induced spin fluctuations. In a recent test experiment we explored the low energy inelastic spectra in the AF2 phase and in the paramagnetic (PM) state under the influence of a magnetic field. The aim of this proposal is to further investigate the temperature and magnetic field dependence of spin fluctuations in the PM state as well as the spin dynamics in the low temperature magnetic phase AF1. The field dependence of the PM state will help us to understand the behaviour of spin fluctuations under field in the AF2 phase. The evolution of the spin dynamics in the AF1 phase is strongly related to transition to the AF2 phase under field and the inverse MCE.
