Abstract The linear thermal expansion, compressibility and magnetostriction of UNiGa have been measured under high pressure. Huge anisotropic behaviors are observed in these physical quantities. The linear thermal expansion coefficients are α a ∼ 16·10−6 K−1 along thea-axis anda c ∼5·10−6 K−1 along thec-axis, and the linear compressibilities at room temperature are κ a ∼ 3.6·10−3 GPa−1 and κ c ∼ 1.7·10−3 GPa−1 alonga-axis andc-axes, respectively. UNiGa orders antiferromagnetically belowT N=39 K and shows a metamagnetic transition at 4.2 K in magnetic fieldB C=1 T. It is found thatT N decreases andB C increases with increasing pressure.
