The photothermally modulated (PM) ferromagnetic resonance (FMR) combines the high sensitivity of conventional FMR and spatial resolution. This technique has been applied to a single-crystalline yttrium iron garnet (YIG) sphere with a diameter of 2 mm. For the first time, the spatial variation of the high-frequency magnetization patterns known as Walker(More)
Business today is increasingly becoming service-driven. A service represents either a part of or a complete business process, which in turn depicts the life cycle of a Business Object (BO). A number of actions constrained by a set of business policies cause the BO to transit from an initial state to a final state during its life cycle. The constraints would(More)
The photothermally modulated (PM) ferromagnetic resonance (FMR) combines the high sensitivity of conventional FMR and the spatial resolution of thermal waves. For the first time, this alternative FMR-technique was applied to the magnetic characterization of high-quality thin Fe (001) films epitaxially grown on (001) GaAs substrate: Images of the(More)
