Lattice dynamics of magnesium on extended de Launay model

“…These kinds of resu]ts are quite superior to those found on other phenomenological models (e.g., UPADHY_&YA and SINHA [20], SHARAN and BAJPAI [4], UPAD-HYAYA and VERMA [5], BOSE et al [21] and on models on first principles (PI~DOnE and RYNN [22], KI~G and CVTLER [6], ROY and u [23] and BROVMAN and KACAN [24]). The computed results have given very good agreement with the experimental ones as far as to say that the maximum deviation found between the caleulated and experimental phonons was never found to be more than 10~/o.…”
