N2 - Polycrystalline (U1-xThx)2Pt2In solid solutions with x=0.03, 0.05, 0.08 and 0.10 were synthesized by arc melting the constituents under a purified Ar atmosphere. All the compounds crystallize in a tetragonal U3Si2-type structure, with the space-group P4/mbm, (Z=2). The effects of Th substitution for U on the magnetic properties suggest pronounced electron correlations as in the heavy fermion U2Pt2In. However, no clear indication of magnetic ordering in all the compounds was found. The magnetic phase transitions around 3 and 19 K, found by means of ac-susceptibility and magnetization measurements are most likely due to the presence of minority phases.
