Electron magnetic resonance linewidths of Gd 3+ in ceria and magnesia were measured in samples doped with small concentrations (up to 1.0 mol%) of Gd. The linewidth was found to change in a predictable way with Gd concentration. The experimental results show that the technique can be used to measure, rapidly and nondestructively, small concentrations of Gd in commercial CeO 2 and MgO.
