Abstract
The temperature dependences of the a axis in-plane resistivity and of the thermopower S along the a and c axes were measured for the single crystals ET2Cu[N(CN)2]Cl1-xBrx (0 less-than-or-equal-to x < 0.5). The most interesting feature of the S-vs-T curves is that for both in-plan e directions the magnitude of S starts to decrease at nearly 35 K and reaches zero at nearly 20 K. This behavior is related to the magnetic phase transition in the salt and is attributed tentatively to the magn etic polaron formation.
