Static magnetization temperature curves in the field cooled (FC) and zero-field cooled (ZFC) regimes. Inset: magnetic susceptibility as a function of temperature on a log-log scale. A power law approximation is shown as a solid curve.
Magnetization isotherms of CoMgGaO2BO3 below and above the magnetic transition. Inset: ac magnetic susceptibility (real component) as a function of temperature for frequencies of 0.1, 0.5, 1, 5, and 10 kHz (top-to-bottom).
The lattice parameters of Co3O2BO3 and CoMgGaO2BO3.
