  We present magnetic susceptibility, heat capacity, and neutron diffraction
measurements of polycrystalline Nd2Ru2O7 down to 0.4 K. Three anomalies in the
magnetic susceptibility measurements at 146, 21 and 1.8 K are associated with
an antiferromagnetic ordering of the Ru4+ moments, a weak ferromagnetic signal
attributed to a canting of the Ru4+ and Nd3+ moments, and a long-range-ordering
of the Nd3+ moments, respectively. The long-range order of the Nd3+ moments was
observed in all the measurements, indicating that the ground state of the
compound is not a spin glass. The magnetic entropy of Rln2 accumulated up to 5
K, suggests the Nd3+ has a doublet ground state. Lattice distortions accompany
the transitions, as revealed by neutron diffraction measurements, and in
agreement with earlier synchrotron x-ray studies. The magnetic moment of the
Nd3+ ion at 0.4 K is estimated to be 1.54(2){\mu}B and the magnetic structure
is all-in all-out as determined by our neutron diffraction measurements.
