In contrast to the interaction between two magnets with opposite magnetization directions,
the interaction between a permanent magnet and a superconductor can be stable and result …

Magnetic bearings are being researched for high-speed applications, such as flywheel
energy storage devices, to eliminate friction losses. As per Earnshaw's theorem, stable …

We review the modeling progress of the magnetic response of hard type-II superconductors
(SCs) using the critical-state model (CSM). We focus on magnetization loops when a uniform …

One of the major experimental difficulties in studying materials at extreme temperatures is
unwanted contamination of the sample through contact with the container. This can be …

After the first man-loading high temperature superconducting (HTS) Maglev demonstration
had been tested successfully years ago, its future application attracts more and more …

The Laboratory for Applied Superconductivity of the Federal University of Rio de Janeiro
(LASUP) has been developing a superconducting magnetic levitation urban train named …

For superconducting coils with many turns, it is widely believed that the magnetic field from
magnetization currents is negligible compared with the one generated by the whole coil …

The characteristics of the permanent magnets composing the guideway in superconducting
magnetic levitation devices are very important for their performance in terms of levitation …

We report a simple, efficient and economical way to enhance the levitation or guidance
performance of present high-temperature superconducting (HTS) Maglev systems by …

Bulk melt-processed Y–Ba–Cu–O (YBCO) has significant potential for a variety of high-field
permanent-magnet-like applications, such as the rotor of a brushless motor. When used in …
