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 the a-axis and a(c) ~ 5 · 10^-6 K^-1 along the c-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 along a-axis and c-axes, respectively. UNiGa orders antiferromagnetically below T(N) = 39 K and shows a metamagnetic transition at 4.2 K in magnetic field B(C) = 1 T. It is found that T(N) decreases and B(C) increases with increasing pressure.
