摘要：

The intermetallic compound TbNiAl which crystallizes in the hexagonal ZrNiAl structure type has been studied by means of neutron powder diffraction. Its magnetic phase diagram turned out to be more complex than reported previously. The antiferromagnetic order below T(N) = 44.6 K can be described by two propagation vectors k1 = (1/2, 0,1/2) and k2 = (1/2,1/2,1/2). A second transition temperature T1 = 23.5 K is found where, most probably, the frustrated spins change direction and/or the magnitude of the moments.
