High-Current Low-Voltage Power Supply for Superconducting Magnets

Émilien Luc Henri Coulinge

In the wide range of applications for power supplies, the ones dedicated to feeding superconducting magnets occupy a niche. This particular kind of magnets has the intrinsic property of having zero resistance, and is only used in high-end facilities for fu ...

Two coupled chains are simpler than one: field-induced chirality in a frustrated spin ladder

Joël Mesot, Shuang Wang

Although the frustrated (zigzag) spin chain is the Drosophila of frustrated magnetism, our understanding of a pair of coupled zigzag chains (frustrated spin ladder) in a magnetic field is still lacking. We address this problem through nuclear magnetic reso ...

Preferential out-of-plane conduction and quasi-one-dimensional electronic states in layered 1T-TaS2

László Forró, Alla Arakcheeva, Luka Ciric, Helmuth Berger, Philip Johannes Walter Moll, Ana Akrap, Andrea Pisoni, Konstantin Semeniuk

Layered transition metal dichalcogenides (TMDs) are commonly classified as quasi-two-dimensional materials, meaning that their electronic structure closely resembles that of an individual layer, which results in resistivity anisotropies reaching thousands. ...

FeO-based nanostructures and nanohybrids for photoelectrochemical water splitting

Kevin Sivula

The need to satisfy the growing global population's enormous energy demands is a major challenge for modern societies. Photoelectrochemical (PEC) water splitting (WS) is seen as a leading strategy for producing an extremely promising renewable store of ene ...

Force Reduction in a Short-Stroke Vibration Tubular Generator for Vehicle Energy Harvesting Application

Minh Trung Duöng

This paper examines methods to reduce the detent force and electromagnetic force in a short-stroke vibration tubular generator used to harvest energy from a vehicle suspension system but still achieve the design targets of power and power density. A well-k ...

Integrated Simulation Approach to Loss Calculations of Power Converter Systems

Drazen Dujic, Min Luo, Nikolina Djekanovic

There is a strong need in the power electronics community to have design tools capable of performing simultaneous simulations in different domains, e.g. electric, magnetic, dielectric and thermal. Therefore, this paper presents an approach to the calculati ...

Force and Torque Model of Ironless Passive Magnetic Bearing Structures

Yves Perriard, Douglas Martins Araujo, Leopoldo Rossini, Guzmán Borque Gallego

This article presents the development and validation of a three-dimensional force and torque semi-analytical model for ironless permanent magnet structures. This method relies on the definition of the magnetic flux density generated by permanent magnets in ...

Magnetic 2D materials and heterostructures

Marco Gibertini

The family of two-dimensional (2D) materials grows day by day, hugely expanding the scope of possible phenomena to be explored in two dimensions, as well as the possible van der Waals (vdW) heterostructures that one can create. Such 2D materials currently ...

Preliminary Tests of Soldered and Diffusion-Bonded Splices Between Nb3Sn Rutherford Cables for Graded High-Field Accelerator Magnets

Pierluigi Bruzzone, Davide Uglietti, Mithlesh Kumar, Vincenzo D'Auria

High-field accelerator magnets of the next generation will require coil grading in order to decrease the amount of superconductor and hence the magnet cost. The joints between Nb3Sn conductor grades must have low electrical resistance (
