Nearly every modern cellphone has a built-in compass, or magnetometer, that detects the direction of Earth’s magnetic field, providing critical information for...
Scientists at the National Institute of Standards and Technology (NIST) with colleagues elsewhere have employed neutron imaging and a reconstruction algorithm...
You might not recognize these two faces from such NIST social media hits as “microprinting with candy” and “molds for microparticles,” but they were behind that...
µMAG advances the state of the art in micromagnetic modeling by establishing and maintaining communications among interested researchers, by defining a collection of standard micromagnetic problems, and by leading the development of a public reference implementation of micromagnetic software....
Micromagnetics technologies constitute the foundation of computer storage devices. Exponential growth in the size of portable magnetic memories accompanied by decrease cost-per-byte is evidence of success in this technology. To sustain this growth engineers and scientists are increasingly using...
Collaborations with industry leaders have led us to develop new measurement techniques to improve our understanding thermal transport, spin transport, and nanoscopic (and interfacial) material properties in active device structures. Such capability requires the ability to measure these properties at...
Here is a brief description of our work with links to recent papers from our investigations, broadly classified as experimental and modeling. A brief overview of Josephson junction-based bio-inspired computing can be found in our review article. Experimental We have facilities to develop our devices...
The intrinsic magnetic susceptibility of noninteracting magnetic nanoparticles is calculated from the measured complex radio-frequency susceptibility of dipolar...
The Heisenberg exchange constant plays a crucial role in determining the switching behavior of magnetic nano-objects, along with the magnetic anisotropy...
