We have investigated the eect of hydrostatic pressure on magnetic properties of TbNiAl, crystallizing in hexagonal ZrNiAl-type structure. TbNiAl orders antiferromagnetically below TN = 45 K and undergoes further magnetic phase transition to another AF phase at T1 = 23 K. The magnetic eld of Bc ∼ = 0.3 T applied along the caxis at 2 K leads to the transition to ferromagnetic order. By applying the hydrostatic pressure, both TN and T1 remain almost unaected whereas Bc shows a strong increase. The
