Abstract : The magnetic susceptibilities of UO2-ThO2 systems measured by Slowinski and Elliott and by Comly are analysed on the simplified models of vibronic system, where non-Kramers paramagnetic ions in triplet ground state interact either with localized tetragonal modes of vibration with sharp frequency, or with those composed of Debye phonons. The susceptibility is simply expressed in terms of a temperature dependent reduction factor which reduces the effective Curie constant and makes the susceptibility deviate from the Curie-Weiss law. Agreement with experiments is fairly good.
