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
A ferromagnetic material such as iron acquires its magnetization because the magnetic orientation of its constituent atoms all line up in the same way. Because individual electrons also have an intrinsic magnetic moment – which is often referred to as the electron “spin” - they can interact with
Magnetic tunnel junctions (see Fig. 1) consist of two thin films of ferromagnetic material separated by a few atomic layers of an insulating material. The insulator is so thin that electrons can tunnel quantum mechanically through it. The rate at which the electrons tunnel is affected by the
A flaw in a crystal might not be an intuitive choice for a measurement tool, but the nitrogen-vacancy (NV-) defect in diamond is something special. Using light, we prepare the NV- center’s the quantum spin state, it interacts with magnetic fields, and we read out the resulting spin state through
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

Image reconstruction is a fundamental step in Magnetic Particle Imaging (MPI). Since it was developed, several methods have been studied to perform more
Nagaoka ferromagnetism (NF) is a long-predicted example of itinerant ferromagnetism (IF) in the Hubbard model that has been studied theoretically for many years
