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 ...
