Notes on phase transitions and the role of spin fluctuations

The physical properties of two chiral systems with localized and delocalized magnetic moments, Cu₂OSeO₃ and MnSi, are reviewed. It is concluded that the longitudinal fluctuations of magnetic moments affect little the qualitative picture of phase transitions and the magnetic phase diagrams of chiral systems.

Keywords: chiral magnetic systems, phase transitions, longitudinal fluctuations of the magnetic moment
