Magnetic Properties of Pure and Doped Gallium Nitride Nanocrystals

Author:

Journal:
JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY


Issue Date:
2017


Abstract(summary):

In the present paper, Ga1-xCoxN, Ga1-xNixN and Ga1-xTbxN (0 <=3D x <=3D 0.1) nanocrystals have been synthesized by a facile solvothermal method. Crystallographic characterization of synthesized materials has been done using powder X-ray diffraction technique. Recorded diffraction patterns reveal the formation of wurtzite (hexagonal) structured GaN nanocrystals. Electron microscopic studies have been carried for the detailed topographical and morphological analyses of synthesized nanomaterials. Recorded electron micrographs indicate the formation of nearly mono-disperse nanoparticles, having average size similar to 4 nm. Magnetic measurements of doped nanocrystals revealed ferromagnetic behavior at room temperature however pure GaN is diamagnetic at room temperature.
