Superconductors and Magnetic Materials

Dear Colleagues,

The expanding interest in decreasing the size and weight of electromagnetic devices and machinery implies the development of high-electromagnetic-power-density materials. This Special Issue focuses on the development and application of improved superconductor compounds, permanent magnets, and high-magnetic-permeability materials for power applications. Also, superconductor nanomaterials for high-sensing magnetic-field detection and quantum computing applications.

Superconductors are typically utilized as bulks and wires or tapes. Superconductor bulks are typically employed due to their ability to store or shield high magnetic field values. Superconductor wires or tapes are used to generate high magnetic fields due to their high current loading capabilities. Therefore, superconductors have been utilized in many applications, such as electrical machines and transformers, magnetic levitation or propulsion, magnetic shielding, electromagnets, superconducting magnetic energy storage and in strong magnets used in magnetic resonance, particle acceleration or collision, and confinement fusion. Also, quantum interference devices for high-sensing magnetic-field detection.

Permanent magnets are employed in electrical machines, and magnetic levitation or propulsion. High-magnetic-permeability materials enable the magnetic flux density in electrical machines, transformers, and electromagnets to be enhanced.

This Special Issue welcomes the submission of studies on the development of material crystals consisting of novel and doped compounds for superconductor bulks, wires and tapes, permanent magnets and high-magnetic-permeability materials. These include superconducting compounds, such as niobium–tin and niobium–titanium, magnesium diboride, cuprates, nickelates, carbon and iron alloys. High-magnetic-permeability materials include soft and hard ferrites, silicon–iron and cobalt–iron alloys. Permanent magnets include alnico, neodymium–iron–boron and samarium–cobalt alloys.

This Special Issue welcomes the contribution of original research papers that address the latest findings in the development and application of superconducting materials and advanced magnetic materials. In addition, we welcome the submission of studies on the variation in the electromagnetic characteristics of new and existing superconducting and magnetic materials in different pressure and temperature operating conditions, the identification of innovative and improved power or magnetic-field sensing applications using existing or novel materials of these types, and the assessment of the utilization of rare-earth-free magnetic materials.
