摘要
The well recognized model potential is used to investigate the vibrational properties of four Fe-based binary glassy alloys viz.Fe_(90)Zr_(10),Fe_(80)B_(20),Fe_(83)B_(17) and Fe_(80)P_(20).The thermodynamic and elastic properties are also computed from the elastic limits of the phonon dispersion curves(PDC).Three theoretical approaches given by Hubbard-Beeby(HB),Takeno-Goda(TG)and Bhatia-Singh(BS)are used in the present study to compute the PDC.Six local field correction functions proposed by Hartree(H),Taylor(T),Ichimaru-Utsumi(IU),Farid et al.(F)and Sarkar et al.(S)and Sarkar et al.’s local field factor(SLFF)based excgange and correlation function are employed to see the effect of exchange and correlation in the aforesaid properties.
