Proximity-Induced Novel Ferromagnetism Accompanied with Resolute Metallicity in NdNiO3 Heterostructure

Joël Mesot, Zoran Ristic, Marco Caputo

Employing X-ray magnetic circular dichroism (XMCD), angle-resolved photoemission spectroscopy (ARPES), and momentum-resolved density fluctuation (MRDF) theory, the magnetic and electronic properties of ultrathin NdNiO3 (NNO) film in proximity to ferromagne ...

Upgrade and Commissioning of the SULTAN Facility to Host Quench Experiments on HTS High Current Conductors

Pierluigi Bruzzone, Rainer Wesche, Boris Stepanov, Kamil Sedlák, Davide Uglietti, Ortensia Dicuonzo

High Temperature Superconductors (HTS) are promising materials for future fusion magnets. One of HTS conductors' main issues is the quench protection: the quench develops much slower than in LTS, delaying the quench detection by voltage monitoring and caus ...

Kubits: Solid-State Self-Reconfiguration With Programmable Magnets

Auke Ijspeert, Mehmet Hasan Mutlu, Simon Lukas Hauser

Even though many prototypes of 3D self-reconfiguring modular robots (SRMRs) have been developed in recent years, a demonstration involving 1'000 modules remains a challenge. This is largely due to complex mechanics needed to achieve connection, disconnecti ...

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 ...
