- 論文の詳細を見る
Thermal expansion in K.Se0. was reexamined in low ternperature region,85 -l70K. Much smaller thermal expansion coefficients in comparison with aprevious report were obtained. The estimation of the pressure (p) coefficient ofthe incommensurate transition temperature T., dT./dp, based upon the presentresult, leads to the value of -8.3 dog/kbar, which agrees well with the reportedexperimental results.Small discontinuity was observed at the incommensur?tte-commensurate(ferroelectric) transition temperature T.=93 K, proving that tltis transition is ofthe first order. The d7'./c3p estimated seems to be also in reasonable agreementwith the previous results.
