Neutron Diffraction studies of skyrmionic A phase and spin fluctuations in fluctuation-disordered phase under extreme conditions in MnSi

Abstract: The study of skyrmion (magnetic vortex) lattice formation below ~30 K in chiral magnet MnSi has gotten very good attention in the recent times. Few of the key questions concerns the thermodynamic stability of A-phase. The stability of A-phase under applied pressure and magnetic fields. The recent studies of Hall Effect on MnSi suggests no effect of pressure on the skyrmion properties. The nature of electron correlations in the metallic state of MnSi under high pressures. The detailed magnetic structural studies by using neutron diffraction studies at extreme conditions low temperature, high pressure and magnetic fields. Thus the constructed phase diagram in T-p space may resolve the ambiguity over the quantum criticality and simultaneous emergence of non-Fermi liquids at critical pressures and stability of A-phase under high pressures.
