Excitation Mechanisms of Er Optical Centers in GaN Epilayers
D. K. George, M. Hawkins, M. McLaren +4
We report direct evidence of two mechanisms responsible for the excitation of optically active Er3+ ions in GaN epilayers grown by metal-organic chemical vapor deposition. These me…

Temperature controlled motion of an antiferromagnet-ferromagnet interface within a dopant-graded FeRh epilayer
C. Le Graët, T. R. Charlton, M. McLaren +7
Chemically ordered B2 FeRh exhibits a remarkable antiferromagnetic-ferromagnetic phase transition that is first order. It thus shows phase coexistence, usually by proceeding though…
