Abstract: High-resolution DC magnetization and AC-specific-heat data of the cubic helimagnet FeGe have been measured as function of temperature and magnetic field. The magnetization data as well as the isothermal susceptibility data confirm the complexity of the magnetic phase diagram in the vicinity of the onset of long-range magnetic order (Tc = 278.5 K) and the existence of a segmented A-phase region. Moreover, these data revealed independent and clear indications of phase boundaries and crossovers within the A-phase region. Together with the anomalies in the specific-heat data around Tc and at small magnetic fields (H < 600 Oe) a complex magnetic phase diagram of FeGe is obtained.
