Neutron scattering and heat capacity techniques were used to investigate two frustrated magnets with similar structure, but different sized spins (S).The research team, led by McMaster University, found the molybdate pyrochlore oxide material, Lu2Mo2O7 (S=1) undergoes a transition to a spin glass ground state, while the oxynitride Lu2Mo2O5N2 (S=1/2) possesses a quantum spin liquid ground
