Abstract

New169Tm Mössbauer and specific heat data recorded for TmCu2Si2 and Tm1/2Lu1/2Cu2Si2 in the temperature range 1.4K to 20K verify that TmCu2Si2 orders magnetically at TN=3K and support earlier conjecture that TmCu2Si2 behaves as a 2-singlet system at low temperatures. However attempts to describe the available data in terms of a single set of parameters suggest that the single-ion and molecular field approximations are an oversimplification of the true situation.
