Abstract
In this study, we reported the structural, electrical and magnetic properties of B-doped LiCrO2.Cr2O3 system by boron doping. XRD pattern of the samples showed that the boron ions were substituted with Cr ions in both lattices and the volume of the cells were decreased by increasing boron content. The particle size and strain calculations were performed by using XRD pattern and it is found that the particle sizes were not changed much by boron doping but the strain were increased by increasing boron in the samples. The susceptibility of the undoped sample shows two different phase behavior with decreasing temperature and it is found that the magnetic properties of Cr2O3 were dominant at room temperature to 100 K and the peak at 62 K was due to the LiCrO2 phase. It should be noted that the boron doping were caused the decrease of the room temperature susceptibility and the antiferromagnetic interactions were destroyed by boron incorporation of the lattice.
