Specific Heat of PbFX (X = Cl, Br, I) at Low Temperature
At very low temperature, below 4 K, the specific heat of PbFCl, PbFBr, and PbFI shows a classical behaviour with a T3 temperature variation. The obtained Debye temperatures follow the Lindemann relation. Between 4 and 35 K, deviations from the T3 law appear and are explained by means of two Einstein...

| description | At very low temperature, below 4 K, the specific heat of PbFCl, PbFBr, and PbFI shows a classical behaviour with a T3 temperature variation. The obtained Debye temperatures follow the Lindemann relation. Between 4 and 35 K, deviations from the T3 law appear and are explained by means of two Einstein oscillators. These oscillators are linked to the low frequency optical phonons.
Au dessous de 4 K, la chaleur spécifique de PbFCl, PbFBr et PbFI présente un comportement classique de Debye. Les températures de Debye observées obéissent à la relation de Lindemann. Entre 4 et 35 K, des déviations à la loi en T3 apparaissent et sont expliquées à l'aide de deux oscillateurs d'Einstein liés à des phonons optiques de basse fréquence. |
