Supplement Number 1

The overview and picture of the laboratory-made ADR cell is described. We display the data of the specific heat in the reference compound La2Cu2In and temperature dependence of the magnetization under various fields in Ce2Cu2In. We also show the field dependence of magnetization and the procedure to refine the absolute values of entropy at zero field and 2 T in x = 0.33 and 0.38.
