We study the dc resistivity of UNi 2 Al 3 thin films as a function of temperature and magnetic field. We focus on the temperature range around the antiferromagnetic transition ( T N ≈4 K in zero applied field). From a clear signature of T N in the dc resistance along the crystallographic a -direction, we extract the shape of the magnetic phase diagram. Here we find quantitative differences in comparison to previous studies on bulk crystals.
