“…The levitation force and trapped field properties of the two samples were measured at liquid nitrogen temperature by a self‐designed 3D magnetic force & field measuring device . Figure presents the levitation force as a function of the distance between the YBCO sample and the permanent magnet (ϕ = 18 mm, B = 0.5 T) for the two samples.…”

Introduction of refined second-phase particles in superconducting YBa 2 Cu 3 O 7 -x (Y-123) matrix is known to be an effective route to improve the dl-type pinning and the performance of Y-Ba-Cu-O (YBCO) single-grain superconductors, while the dT c -type pinning induced by spatial fluctuations in matrix composition is also important and contributes to the in-field J c performance and high-field applications of bulk superconductors.

“…Microstructure of the PSPP and the single-domain GdBCO bulks were investigated by a scanning electron microscope (SEM). e levitation forces of the GdBCO bulks were measured at 77 K under a zero-field cooling state by self-designed magnetic force and magnetic field measurement system [16]. Figure 1 is the morphology of the PSPP with the same initial new solid phase source of (Gd 2 O 3 + BaCuO 2 ) sintered at different temperatures.…”

In this paper, single-domain GdBCO bulks have been fabricated by a new Gd + 011 TSIG method with precursor solid phase pellets (PSPPs) of different Gd211 particle sizes and distributions, prepared by solid state reaction with well-mixed (Gd2O3 + BaCuO2) pellets at different temperatures. The novel results indicated that (1) the average size of Gd211 particles in PSPP is monotonically increasing with increasing the sintering temperature up to 1200°C. (2) With increasing the sintering temperature from 950 to 1200°C, the porous ratio and the density of the PSPP are, respectively, monotonically decreasing and increasing. Furthermore when the sintering temperature is less than 1000°C, the porous ratio is higher and the density is lower than the values of the pressed pellets. (3) With increasing the sintering temperature, the average size of Gd211 particles in the GdBCO bulk first decreases and then increases. In addition, the smallest Gd211 particles are obtained in the sample sintered at 1050°C. (4) The maximum levitation force is obtained in the sample sintered at 1150°C with a relatively larger size of Gd211 particles and lower porosity. This result is significant when fabricating high-quality GdBCO bulk superconductors by controlling the porosity, Gd211 particle size, and their distribution characteristic.

“…The performance of the whole bulk sample including levitation force and trapped field were measured at the temperature of liquid nitrogen by a self-designed 3D magnetic force & field measuring device [32]. A cylindrical NdFeB permanent magnet with a diameter 18 mm and a surface field 0.5 T was used for measurement of levitation force and the maximum levitation force was achieved at the smallest distance (0.5 mm) between the nearest surfaces of the zero-field cooled sample and the magnet.…”
