Neutron diffraction, Mössbauer spectroscopy, magnetometry, and in-field x-ray diffraction are
employed to investigate the magnetoelastic phase transition in hexagonal (Mn, Fe) 2 (P, Si)
compounds.(Mn, Fe) 2 (P, Si) compounds undergo for certain compositions a second-order
paramagnetic (PM) to a spin-density-wave (SDW) phase transition before further
transforming into a ferromagnetic (FM) phase via a first-order phase transition. The SDW-FM
transition can be kinetically arrested, causing the coexistence of FM and untransformed …
