Temperature-dependent electron paramagnetic resonance detect oxygen vacancy defects and Cr valence of tetragonal Ba(Ti1−xCrx)O3 ceramics
Temperature-dependent electron paramagnetic resonance (EPR) study was employed to detect oxygen vacancy defects in the tetragonal Ba(Ti1−xCrx)O3 (x = 5%) ceramic for the first time. In the rhombohedral phase below −150 °C, an EPR signal at g = 1.955 appeared in the insulating Ba(Ti1−xCrx)O3 (x = 5%)...
