(a) X-ray diffraction patterns for a film on without a buffer layer. Known diffraction peaks are indexed. (b) (006) pole figure of film. The legend for the contours is shown on the right with 1.0 indicating random orientation. Scans were done in every 2.5° angular grid.
(Color online) Comparison of (006) pole figures of films: (a) thicker films deposited onGaN. (b) thick films deposited at on GaN, and (c) thick films deposited at with a MgO buffer layer on GaN.
(a) SEM micrograph of as-deposited (002) film and a cartoon showing dispersion of the axes from the direction of the film normal. (b) Schematic of geometry of vector VSM for torque magnetometry of perpendicular films.
(Color online) (a) Easy and hard axis magnetization curves and components of the magnetization normal to the applied field for the high deposition temperature (002) film (b) for the low deposition temperature (002) film, and (c) for a (002) film.
(Color online) (a) Comparison of data for a and for a film fitted to Eq. (2b) and (b) magnetization trajectory for the film.
