Abstract
A simple hydrothermal approach was used to effectively synthesize high-quality single crystal hematite (α-Fe2O3) nanorods with an average diameter of ∼59.40 nm. Rietveld refinement analysis was used to examine the crystal structure and phase purity of hematite that displayed a hexagonal crystal structure with a single phase in the R-3c space group. Unit cell and other reliability parameters were also determined using Rietveld refinement. In addition, magnetic measurements using a vibrating sample magnetometer (VSM) have been conducted at room temperature from which magnetic hysteresis loops reveal that the material is weakly ferromagnetic with lowered magnetic parameter values. In the synthesized sample, both ferromagnetic (FM) and antiferromagnetic (AFM) contributions were observed and separated by applying a theoretical modification of the measured M-H loop.
