Effects of initial cooling conditions and measurement heights on the levitation performance of bulk MgB superconductor at different measurement temperatures
(Springer/Plenum Publishers, 2014)
The levitation properties of MgB prepared by hot press at 200 C and then pellet/closed tube method has been investigated. the vertical and lateral levitation forces ( and on a cylindrical NdFeB permanent magnet (PM) below ...
Comparison of levitation forces of bulk MgB2 superconductors produced by nano boron and carbon-doped nano boron
(Springer, 2014)
MgB2 bulk superconductors were prepared by hot press plus furnace heating method. Two types of boron powders were used, one is amorphous nano boron and the other is C-doped boron. Characteristics of superconductors were ...
Effect of adding on the critical current density and lateral levitation force of bulk
(Springer/Plenum Publishers, 2015)
We fabricated malic acid -added bulks by wet mixing and "Two-step solid state reaction method". the effects of adding malic acid on , behaviour and lateral levitation force features of bulk have been investigated. A ...
High-field pinning potential in YBCO films with nanoengineered pinning centres
(Springer, 2015)
Frequency-dependent AC susceptibility measurements have been used to estimate the critical current densities and pinning potential of two 1.1-mu m-thick YBCO films with nanoengineered pinning centres. the films were grown ...
The size effect on the magnetic levitation force of MgB2 bulk superconductors
(Elsevier Sci Ltd, 2016)
In this study, the size effect on the magnetic levitation performance of disk-shaped MgB2 bulk superconductors and permanent magnets was investigated. MgB2 samples with varying diameters of 13 mm, 15 mm and 18 mm, each of ...
