Anisotropy of transport properties of novel Kondo ferromagnet UAsSe

Anisotropy of the thermoelectric power, S(T), Hall resistivity and magnetor esistivity. MR, of UAsSe single crystals were examined in the temperature r ange 4.2-300 K and ill magnetic Held up to 14 T. The Following phenomena ar e considered as the ones confirming the UAsSe as the novel Kondo ferromagne t. The normal Hall coefficient shows T-1/2 dependence. The S(T) behaves lik e the one formed of both ferromagnetic metal and Kondo S(T) components. The longitudinal and transverse MRs are positive and negative, respectively, a nd of order similar to \0.3\% per T at 4.2 K. (C) 2000 Elsevier Science B.V . All rights reserved.
