A comparative study of thermal properties of SmFeAsO, SmFeAs(O0.93F0.07) andSmFeAs(O0.85F0.15) samples is presented. Specific heat and thermal conductivityshow clear evidences of the spin density wave (SDW) ordering below TSDW 135 Kin undoped SmFeAsO. At low level of F-doping, SmFeAs(O0.93F0.07), SDW orderingis suppressed and superconducting features are not yet optimally developed inboth specific heat and thermal conductivity. At optimal level of F-dopingSmFeAs(O0.85F0.15) anomalies related to the superconducting transition are wellnoticeable. By a compared analysis of doped and undoped samples we concludethat, despite F-doping modifies definitely the electronic ground state, it doesnot substantially alter phonon and electron parameters, like phonon modes,Sommerfeld coefficient, electro-phonon coupling. The analysis of the thermalconductivity curves provides an evaluation of SDW and superconducting energygap, showing that phonons can suitably probe features of electronic groundstate.
