Abstract
Thermopower S vs temperature dependences were measured for single crys tals ET(2)Cu[N(CN)(2)]Cl. Magnetic field of 14 T shifts the S(T) curve to high temperatures. This behaviour is ascribed tentatively to the t ransport by the magnetic polarons (ferrons), the domains around free c arriers that appear as ferromagnetically ordered regions in the antife rromagnetically ordered matrix and are stabilized by the magnetic fiel d above the magnetic transition in the material. A peculiar zero value of the S is interpreted as an evidence for a collective motion of the se quasiparticles.
