Dynamical magnetism in the disordered cubic lattice material $\gamma$-${\mathrm{Ba}}_3{\mathrm{CoNb}}_2{\mathrm{O}}_9$

Fanjun Xu, Ralf Feyerherm, Cecilie Glittum +12

$\gamma$-${\mathrm{Ba}}_3{\mathrm{CoNb}}_2{\mathrm{O}}_9$ realizes a disordered simple-cubic spin-$1/2$ lattice in which Co${}^{2+}$ ions randomly occupy one third of the sites, placing the system…
