A method for measuring the magnetostriction of thin films using a vibrating sample
magnetometer is described. We describe the design of a custom sample holder to apply an
adjustable bending stress to the sample during measurement and observe the resulting change in
the M-H loop.
Ferromagnetic resonance (FMR) characterization, using a vector network analyzer (VNA), is widely used to determine anisotropy, g-factor, and Gilbert damping parameter of magnetic thin films, but results are typically reported without calculation of the measurement accuracy. We present a method of processing VNA-FMR measurements to determine both the value and...
A novel patterning technique that creates magnetization patterns in a continuous magnetostrictive
film with surface acoustic waves is demonstrated. Patterns of 10 μm wide stripes of alternating
magnetization and a 3 μm dot of reversed magnetization are written using standing and focusing
acoustic waves, respectively. The magnetization pattern is size-tunable,...
The ocean plays a critical role in supporting human well-being, from providing food, livelihoods and recreational opportunities to regulating the global climate. Sustainable management aimed at maintaining the flow of a broad range of benefits from the ocean requires a comprehensive and quantitative method to measure and monitor the health...
