摘要：

Measurements of transport properties (resistivity, Seebeck coefficient, thermal conductivity), thermal expansion, heat capacity and magnetic susceptibility of Tb2Mo3Si4 samples with different annealing conditions show that in this superconductor (with T(c) between 0.5 and 1.2 K) a complex magnetic structure exists in the normal state, characterized by transitions at 2.3 K and 19 K. The expected magnetic structures are discussed taking into account the absence of experimental evidence of spontaneous magnetization and the possibility of an antiferromagnetic-structure formation without change of translational geometry.
