The temperature evolution of the chemical and magnetic sublattice of bismuth ferrite has been investigated by neutron scattering below room temperature. Although the bulk lattice structure performed as expected, anomalies were measured in the local B

Double-perovskite iridates A${}_{2}{\mathrm{ZnIrO}}_{6}$ (A=alkaline or lanthanide) show complex magnetic behaviors ranging from weak ferromagnetism to successive antiferromagnetic transitions. Here we report the static (dc) and dynamic (ac) magnetic

We report on comprehensive results identifying the ground state of a triangular-lattice structured YbZnGaO$_4$ to be spin glass, including no long-range magnetic order, prominent broad excitation continua, and absence of magnetic thermal conductivity
