Special Issue Information

Dear Colleagues,

Much of the effort involved in superconducting innovation is centered on high-temperature superconductors (HTS) and, within this field, on REBa2Cu3O7−δ (REBCO) compounds. These materials are the resources used for the preparation of second-generation (2G) high-Tc superconducting tapes, known as coated conductors (CCs), crucial for high-field magnets, motors, generators, and fault current limiters. The aim of this Special Issue is to optimize their performance while reducing production costs.

Traditional methods, like metal–organic chemical vapor deposition (MOCVD), pulsed laser deposition (PLD), and sputtering, have been the go-to options for REBCO films. However, chemical techniques, particularly chemical solution deposition (CSD), have emerged as cost-effective alternatives, enhancing film quality and cost efficiency.

Meanwhile, research continues to explore novel applications for low-temperature superconductors (LTS), which are currently practical only when immersed in a liquid helium bath. The high-energy physics community has recently rekindled interest in Nb3Sn, particularly for the development of dipole and quadrupole magnets intended for the LHC upgrade (Hi-Lumi LHC) and the Future Circular Collider (FCC) at CERN.

Between these two extremes, other superconducting materials with intermediate TC values exist that may have specialized applications. A prime example is MgB2, already employed in magnetic resonance imaging (MRI) machines and previously tested for the creation of fault current limiters. With a Tc of approximately 40 K, it is suitable for applications in the 15–20 K range, achievable via cryocoolers or liquid hydrogen–neon environments.

Iron-based superconductors (IBS) are emerging as promising candidates for various applications. These materials include a wide number of phases with diverse crystal structures and TCs. What unites them is the presence of an active layer where iron is bonded to either arsenic or chalcogenides, such as selenium or tellurium. Owing to their exceptional in-field properties, several phases of IBS have demonstrated significant potential for future practical applications and device fabrication, operating across a wide temperature range, i.e., from 4.2 to 30 K.

This Special Issue of Crystals welcomes research papers presenting groundbreaking ideas and methods to further advance the knowledge of superconducting materials, superconductivity, superconductors, superconducting tapes, coils, and flux pumps, thus propelling superconducting devices into the future.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
