The magnetic properties of the hyperkagome system of Tb3 Ga5 O12 have been investigated by neutron scattering. Evidence of antiferromagnetic long-range order of the Tb moments at TN ≤0.35K in zero field is provided. With the application of magnetic field in the paramagnetic phase, ferromagnetic peaks initially appear at nuclear Bragg reflections. With the field higher than 3 Tesla, antiferromagnetic Bragg peaks appear as well indicating that the low-temperature magnetic phase extends well beyond the phase boundary, into the paramagnetic phase, with field. The new magnetic symmetry sets in at the metamagnetic transition in this system.
