摘要： Systems and methods for spin-based detection of electromagnetic radiation at terahertz and sub-terahertz frequencies is provided. The detector can include a heterostructure, a magnetic field generator, and an electrical circuit. The heterostructure can include a first layer formed of an antiferromagnetic material (AFM) in contact with a second layer of a heavy metal (HM) or a topological insulator. The magnetic field generator can generate a magnetic field oriented approximately parallel to an easy axis of the first layer and approximately parallel to a propagation direction of electromagnetic radiation. The circuit can be in electrical communication with the second layer. The first layer can inject a spin current into the second layer in response to receipt of electromagnetic radiation having a sub-terahertz or terahertz frequency. The second layer can convert the injected spin current into a potential difference. The circuit can be configured to output a signal corresponding to the potential difference.

摘要： A method for the hot measuring of a transverse size of a metal profile to obtain a diameter and/or a mean thickness includes providing power with a sinusoidal current having at least two frequencies, a transmission element having at least two sections distinct and spatially separated from each other and disposed along a nominal axis of feed of the metal profile, generating an electromagnetic field with a desired profile of the force lines, and detecting a signal relating to the variations of the electromagnetic field due to the passage of the metal profile through the sections of the transmission element using a reception element having one or more sections distinct and spatially separated from each other and disposed along the nominal axis in a position of the transmission element.

摘要： A method for probing the properties of nanoscale materials, such as 2D materials or proteins, via nanometer-scale nuclear quadrupole resonance (NQR) spectroscopy using individual atom-like impurities in diamond. Coherent manipulation of shallow nitrogen-vacancy (NV) color centers enables the probing of the NQR spectrum of nanoscale ensembles of nuclear spins. Measuring the NQR spectrum at different magnetic field orientations and magnitudes and fitting to a theoretical model allows for the extraction of atomic structural properties of the material with nanoscale resolution.

摘要： Systems and methods are provided for analyzing magnetic hysteresis of anisotropic magnetic materials. Magnetic hysteresis loops associated with a local coordinate of a coordinated system based on a magnetic field successively applied to each principal axis with an isotropic vector play model are determined. A relaxation factor associated with the convergence behaviors of estimated solution points is applied along with a correction, either a magnetic field correction or a flux density correction, to determine target points on magnetic hysteresis loops. An error between magnetic hysteresis loops and the estimated solution points is determined. The iteration process continues up to a preset number of iterations with alternating correction schemes based on the determined error.

摘要： Systems and methods include determining energy usage of a residence from a current that flows through a first main conductor and a second main conductor that transport the current into the residence. Embodiments of the present disclosure relate to sensors (130a-b) that monitor magnetic fields (150a-b) generated by the first and second main conductors (120a-b). After a resistive load (210a-b) is added for an electrical path in the residence, the first and second magnetic fields (150a-b) may be converted to generate first and second calibrating currents. A first prototype current is corrected to eliminate the influence of the second magnetic field (150b) onto the first magnetic field (150a) and a second prototype current is corrected to eliminate the influence of the first magnetic field (150a) onto the second magnetic field (150b). The energy usage of the residence is determined from the corrected currents.
