Third series. B, Condensed matter and materials physics}, month = {Nov}, note = {We study low-temperature properties of Pr1−xLaxPb3 with the ground state of a non-Kramers Γ3 for 0≦x≦0.8. From the concentration dependence of the specific heat, quadrupolar ordering is expected to occur only up to x∼0.02. 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.}, pages = {012409-1--012409-4}, title = {La impurity effects on quadrupolar ordering in PrPb3}, volume = {65}, year = {2001}, yomi = {ミトウ, マサキ} }
