Using the simplest two-subband Stoner model, it is shown that the variation of the Fermi energy under applied magnetic field is inverse proportional to the spontaneous magnetization and hence most pronounced close to the critical Stoner condition, that is to the quantum critical point of ferromagnetic transition. The perspectives of this result for magnetic tuning of tunnel conductivity in spintronics devices is discussed.
