N2 - UNi2/3Rh1/3Al, a solid solution of UNiAl (Antiferromagnet (AF) with TN-19.3 K) and URhAl (Ferromagnet (F) with TC-27 K) exhibits no magnetic order due to a delicate balance of AF and F interactions. We report on a single-crystal susceptibility χ, magnetization M and resistivity ρ study. The huge uniaxial magnetic anisotropy typical for the parent compounds is preserved in UNi2/3Rh1/3Al. The χc vs. T (ρ vs. T) data exhibit a maximum (minimum) at 10 K. The Mc(B) curve at 1.6 K has a pronounced S-shape with an inflection around 12 T. The increase of ρ with decreasing T below 10 K is removed by magnetic fields. The low-T anomalies are attributed to proximity of magnetic order and AF correlations. The NFL features indicated earlier on polycrystals are not fully confirmed by single-crystal data.
