A significant phonon softening with increasing temperature has been established. The greatest phonon softening for iron atoms is shown to occur in the region of long-wavelength acoustic phonons, for the acoustic branches near the boundary of the Brillouin zone, and for the low-lying weakly dispersive optical branches. The results obtained are analyzed in terms of the views that relate the change in the phonon density of states of iron atoms to the temperature evolution of the electronic density of state for the compound. 000187999 536__ $$0G:(DE-HGF)POF2-54G24$$a54G - JCNS (POF2-54G24)$$cPOF2-54G24$$fPOF II$$x0 000187999 588__ $$aDataset connected to CrossRef, juser.fz-juelich.de 000187999 65027 $$0V:(DE-MLZ)SciArea-120$$2V:(DE-HGF)$$aCondensed Matter Physics$$x0 000187999 65017 $$0V:(DE-MLZ)GC-2004-2016$$2V:(DE-HGF)$$aBasic research$$x2 000187999 65017 $$0V:(DE-MLZ)GC-150-1$$2V:(DE-HGF)$$aKey Technologies$$x1 000187999 65017 $$0V:(DE-MLZ)GC-180$$2V:(DE-HGF)$$aOthers$$x0 000187999 693__ $$0EXP:(DE-MLZ)External-20140101$$5EXP:(DE-MLZ)External-20140101$$eExternal Measurement$$x0 000187999 7001_ $$0P:(DE-HGF)0$$aAlekseev, P.
