摘要：

We report the results on the magnetoresistance and thermoelectric power in a single crystal of UCoAl exhibiting metamagnetic transition at H(M)( similar to 1 T). The longitudinal (transverse) magnetoresistance shows a step-like increase (decrease) across H(M) with increasing field. Thermoelectric power also shows a sharp change Delta S similar to 10 mu V/K (at 4.5 K) across H(M) From these results, we inferred that the high field state is a 5f-band split ferromagnetic state.
