The A2B2X7 pyrochlores (X = O, F), materials containing A- & B-site sublattices of corner-sharing tetrahedra, offer a rich playground in the frustrated magnetism community due to the plethora of exotic magnetic ground-states (eg., spin-ice, spin-glass and spin-liquid states). In particular, the utilization of low-spin (S = ½) magnetic ions on the pyrochlore lattice is of interest due to their large quantum fluctuations at low temperature, which serve to destabilize long-range magnetic order, potentially resulting in a disordered, dynamic highly-correlated quantum spin-liquid ground-state. I will present the structural, magnetic and thermodynamic properties of the new pyrochlore fluoride family NaCdM2F7  (M = Ni, Mn, Co, Cu), setting the main focus on the most interesting members of this family with low-spin magnetic ions Cu (NaCdCu2F7, S = ½ - quantum spin liquid candidate) and Co (NaCdCo2F7, S_eff = ½ - spin glass below Tf = 4.0 K), comparing them with the previously investigated members.
