“…The higher levitation force, stronger trapped field, and self stable levitation properties of single domain REBCO bulk superconductors give them great value and wide applicability in many fields, such as high field permanent magnets [1][2][3], superconducting magnetic bearings and flywheel energy storage systems [4][5][6][7], motors and generators [8,9], and maglev systems [10][11][12][13][14][15].…”

High quality single domain YBCO bulk superconductors, 20 mm in diameter, have been fabricated using a new top seeded infiltration and growth method (called the RE + 011 TSIG method), with a new solid phase (Y2O3 + xBaCuO2) instead of the conventional Y2BaCuO5 solid phase, x = 0, 0.5, 1.0, 1.2, 1.5, 1.8, 2.0, 2.5, 3.0. The effects of different BaCuO2 contents x on the growth morphology, microstructure, and levitation force have been investigated. The results show that the levitation force of the YBCO bulks first increases and then decreases with increasing x, and reaches maximum levitation forces of about 49.2 N (77 K, 0.5 T, with the traditional liquid phase of YBa2Cu3Oy + 3 BaCuO2 + 2 CuO) and 47 N (77.3 K, 0.5 T, with the new liquid phase of Y2O3 + 10 BaCuO2 + 6 CuO) when x = 1.2, which is much higher than that of the samples fabricated with the conventional solid phases (23 N). The average Y2BaCuO5 particle size is about 1 μm, which is much smaller than the 3.4 μm in the samples prepared with the conventional Y2BaCuO5 solid phase; this means that the flux pinning force of the sample can be improved by using the new solid phase. Based on this method, single domain YBCO bulks 40 mm, 59 mm, and 93 mm in diameter have also been fabricated using the TSIG process with the new solid phases (Y2O3 + 1.2BaCuO2). These results indicate that the new TSIG process developed by our lab is a very important and practical method for the fabrication of low cost, large size, and high quality single domain REBCO bulk superconductors.

“…If a long magnetic rail loop is constructed, a superconductor can move along the rail while levitating. This is called a superconducting train or a maglev vehicle [2][3][4], and is a popular science demonstration.…”

We have constructed a magnetic rail system that allows a superconductor to travel in a loop for a long time, similar to a maglev train. The system incorporates a Lego Mindstorms-controlled escalator that automatically cools the superconducting train with liquid nitrogen after each lap. As a result, the superconducting train is able to run continuously for over an hour. This demonstration will motivate students to learn physics and materials science.

“…REBCO superconductors are used, for example, in thin layers and films [28,29], second generation superconducting wires [30][31][32], or as the bi-functional catalyst for hydrogen evolution and oxygen reduction [33]. REBCO bulk ceramic is used in magnetic levitation objects for many applications [34,35], e.g., in precise positioners [36] or superconducting magnetic bearings [37].…”

Nanosized Pinning Centers in the Rare Earth-Barium-Copper-Oxide Thin-Film Superconductors

Since the discovery of high-temperature superconductivity, significant progress in the fabrication of REBCO-based (Rare Earth Barium Copper mixed Oxides) thin-films superconductors has been achieved. In our review, we described the approaches and possibilities of the improvement of superconducting properties by the introduction of nanosized pinning centers. We focused on the synthesis and viability of the material for artificial pinning centers and methods used for the introduction of the pinning centers into superconducting REBCO-based thin-films. This article summarizes available materials and procedures regardless of the financial cost of the individual method. According to available literature, the most significant superconducting REBCO tapes can be obtained when a combination of 1D and 0D nanoparticles are used for nanoscale pinning.
