  The critical behavior of the cubic helimagnet FeGe was obtained from
isothermal magnetization data in very close vicinity of the ordering
temperature. A thorough and consistent scaling analysis of these data revealed
the critical exponents $\beta=0.368$, $\gamma=1.382$, and $\delta=4.787$. The
anomaly in the specific heat associated with the magnetic ordering can be well
described by the critical exponent $\alpha=-0.133$. The values of these
exponents corroborate that the magnetic phase transition in FeGe belongs to the
isotropic 3D-Heisenberg universality class. The specific heat data are well
described by ab initio phonon calculations and confirm the localized character
of the magnetic moments.
