Weak itinerant antiferromagnetism of UNiAl is rapidly suppressed by Fe doping. Magnetic order reappears as weak ferromagnetism in UNi_(0.75)Fe_(0.25)Al. The onset of magnetism can be shifted by H absorption. UNi_(0.85)Fe_(0.15)Al hydride is an antiferromagnet with T_N approx. 70 K. Hydrogenating UNi_(0.70)Fe_(0.30)Al produces a ferromagnet (T_c = 90 K). Here we describe the compound with 20% of Fe and its hydride. The proximity to magnetism shows up as non-Fermi liquid behavior, detected in specific heat as upturn, followed down to 0.3 K, which is gradually suppressed in magnetic fields of several tesla. The hydride was found rather unstable, releasing H at ambient conditions, which made it unsuitable for the specific heat measurement. Magnetization study detected that the hydride shows up as ferromagnet T_c ≈ 98 K.
