magnetism modification and characterization of GaN-based materials using ion beam technology and formation of the nano structure by implanting Mn+ or Co+ ion of different doses into the film samples.SQUID and AGM were used to measure the magnetic properties
such as coercivity and saturation magnetization
for the samples before and after annealing
M-H and M-T curves showed ferromagnetism in the films at both low temperature and room temperature.RBS/C
PIXE and XRD were used to analyze the microstructure
content of doping transition metal and damage.The nano-cluster of ferromagnetism particle was observed under HRTEM.
