Above the transition temperature T t (~258K), the EPR results indicate that MgTi2O4 is paramagnetic. The parameters of the EPR spectra show an anomalous change at T t. The clear EPR lines can be observed in temperature between T t and 220K. Besides that the EPR intensity, g value, and EPR linewidth increase with decreasing temperature; in temperature range below 220K, no clear EPR line can be detected. The EPR spectra results demonstrate that magnetic spin-singlet state and the orbital density wave of MgTi2O4 system are formed gradually with decreasing temperature at low temperature range.
