Magnetic and chemical nonuniformity in Ga[1-x]Mn[x]As films as probed by polarized neutron and x-ray reflectometry
B. J. Kirby, J. A. Borchers, J. J. Rhyne +9
We have used complementary neutron and x-ray reflectivity techniques to examine the depth profiles of a series of as-grown and annealed Ga[1-x]Mn[x]As thin films. A magnetization g…
Neutron diffraction study of average and local structure in La0.5Ca0.5MnO3
E. E. Rodriguez, Th. Proffen, A. Llobet +2
We used neutron powder diffraction to obtain the local and long-range structure of La0.5Ca0.5MnO3 at room temperature and 20K. By combining Rietveld and pair distribution function…
Effects of Capping on the (Ga,Mn)As Magnetic Depth Profile
B. J. Kirby, J. A. Borchers, J. J. Rhyne +6
Annealing can increase the Curie temperature and net magnetization in uncapped (Ga,Mn)As films, effects that are suppressed when the films are capped with GaAs. Previous polarized…
Annealing-Dependent Magnetic Depth Profile in Ga[1-x]Mn[x]As
B. J. Kirby, J. A. Borchers, J. J. Rhyne +7
We have studied the depth-dependent magnetic and structural properties of as-grown and optimally annealed Ga[1-x]Mn[x]As films using polarized neutron reflectometry. In addition to…
Tricritical Point and the Doping Dependence of the Order of the Ferromagnetic Phase Transition of La1-xCaxMnO3
D. Kim, B. Revaz, B. L. Zink +3
We report the doping dependence of the order of the ferromagnetic metal to paramagnetic insulator phase transition in La1-xCaxMnO3. At x = 0.33, magnetization and specific heat dat…
