Effects of silver doping on magnetic levitation performance of MgB2 superconductors
(Elsevier Sci Ltd, 2020)
MgB2 bulk samples with the silver contents of 0, 1.5, 3.0, 4.5, 6.0, 9.0 and 12.0 wt% were fabricated at 775 degrees C for 3 h in Ar atmosphere by solid-state reaction method. the structural and electromagnetic properties ...
Bulk MgB2 superconductor for levitation applications fabricated with boron processed by different routes
(Elsevier, 2023)
Bulk MgB2 discs were prepared by an in situ route from mixtures of magnesium and boron powders. The boron powders were produced by two methods. The first one consisted of a self-propagating high tem-perature magnesiothermic ...
Investigation of MgB2 bulk superconductors synthesized by in situ spark plasma sintering at different temperatures
(Elsevier, 2023)
In this research, the synthesis of MgB2 bulk superconductor with in-situ spark plasma sintering technique at different temperatures and the impacts of these sintering temperatures on the critical parameters (density, phase ...
Enhancing magnetic levitation and guidance force and weight efficiency of high-temperature superconducting maglev systems by using sliced bulk YBCO
(Wiley, 2023)
We aimed to enhance the magnetic force efficiency of Maglev systems without increasing total weight. For this aim, we divided YBCO bulks into three slices horizontally to utilize the YBCO-permanent magnetic guideway (PMG) ...
Levitation force at different temperatures and superconducting properties of nano-structured MgB2 superconductors
(Elsevier, 2010)
The levitation and pinning force properties of nanocrystalline MgB2 superconductors prepared by a mechanical alloying technique with varying milling duration have been investigated. Levitation force measurements under ...
