A large 6.5% hardening of the B_1g(Fe) phonon mode is attributed to the suppression of local fluctuations of the iron spin state with the gradual decrease of the iron paramagnetic moment. The ab-initio lattice dynamic calculations support this conclusion. The enhancement of the low-frequency spectral weight above the structural phase transition temperature T_s and its change below T_s is discussed in relation with the opening of an energy gap between l","authors_text":"Alexander Gusev, Alexander Vasiliev, Dirk Wulferding, Dmitry Chareev, Peter Lemmens, Tatiana Shevtsova, Vladimir Gnezdilov, Yurii G.
