The small length (volume) discontinuity at the magnetic phase transition in MnSi decreases with application of magnetic field to a value $\\Delta L/L \\sim 10^{-7}$, and then suddenly the discontinuity seemingly jumps to zero. Thermal expansivity peaks strongly deteriorate with magnetic fields. No specific features identifying a tricritical point were observed. We propose that the Frenkel concept of heterophase fluctuations may be relevant in the current case. T","authors_text":"A.E. Petrova, S.M.
