Abstract :
We report on the magnetization of the heavy-fermion superconductor UNi2Al3 measured at 1.5 and 4.2 K in magnetic fields up to 35 T. The results indicate in-plane type of magnetocrystalline anisotropy. At both temperatures, almost linear magnetization curves up to the highest field applied are found. In 35 T, we obtained magnetization values of 0.32 μB/f.u. at 1.5 K and 0.30 μB/f.u. at 4.2 K
