The singlet ground state magnetism in pyrochlore osmates Y₂Os₂O₇ and Ho₂Os₂O₇ is studied by DC and AC susceptibility, specific heat, and neutron powder diffraction measurements. Despite the expected non-magnetic singlet in the strong spin-orbit coupling (SOC) limit for Os⁴⁺ (5d⁴), Y₂Os₂O₇ exhibits a spin-glass (SG) ground state below 4 K with weak magnetism, suggesting possible proximity to a quantum phase transition between the non-magnetic state in the strong SOC limit and the magnetic state in the strong superexchange limit. Ho₂Os₂O₇ has the same structural distortion as occurs in Y₂Os₂O₇. However, the Os sublattice in Ho₂Os₂O₇ shows long- range magnetic ordering below 36 K. We find that the sharp difference of the magnetic ground state between Y₂Os₂O₇ and Ho₂Os₂O₇ signals the singlet ground state magnetism in R₂ Os₂ O₇ is fragile and can be disturbed by the weak 4f—5d interactions.
