Abstract

We study low-temperature properties of (formula presented) with the ground state of a non-Kramers (formula presented) for (formula presented) From the concentration dependence of the specific heat, quadrupolar ordering is expected to occur only up to (formula presented) For a wide range of La concentrations where the ordering is absent, the specific heat shows a T linear variation, which is in an excellent agreement with the result obtained by the model for amorphous materials with a random configuration of a two-level system. Impurity effects on quadrupolar moments will be discussed.
