Improvement of superconducting properties of MgB2 by changing the argon ambient pressure and sintering conditions
(Institute of Physics Publishing, 2009)
We have investigated various characteristic properties depending on sintering conditions of MgB2 samples prepared by the standard solid state reaction method. It is inferred from experimental results that the crystallinity ...
Analysis of indentation size effect (ISE) behavior in low-load Vickers microhardness testing of (Sm123)(1-x)(Nd123)(x) superconductor system
(Springer, 2013)
Indentation size effect (ISE) for (Sm123)(1-x) (Nd123)(x) superconducting samples which were fabricated by the solid state reaction technique for values of x = 0.00, 0.05, 0.10, 0.20, and 0.30 was investigated by analyzing ...
Magnetization of Gd diffused YBa2Cu3O7-x superconductor: experiment and theory
(Iop Publishing Ltd, 2013)
The magnetization of Gd diffused YBa2Cu3O7-x is measured by a vibrating sample magnetometer (VSM) at selected temperatures (5, 25, 50, 77 K). the experimental results for the magnetization are analyzed in the critical state ...
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 ...
Investigation on the levitation force behaviour of malic acid added bulk MgB2 superconductors
(Elsevier, 2014)
The effects of malic acid addition (from 0 to 15 wt% of the total MgB2) on the levitation force properties of bulk MgB2 have been investigated. All samples were prepared from magnesium powder, amorphous boron powder, malic ...
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 ...
The effect of magnetic field distribution and pole array on the vertical levitation force properties of HTS maglev systems
(Ieee-Inst Electrical Electronics Engineers Inc, 2015)
In this paper, the levitation force measurements have been carried out by the magnetic force measurement system under both field-cooling and zero-field-cooling regimes, whereas the magnetic field distribution over the ...
Magnetic levitation force and trapped field properties of multiseeded YBCO with triangular arrangement of seeds
(Wiley, 2021)
Although there are studies in literature using different number of seeds with different arrangements, especially line and rectangular, it is seen that there is no detailed study handling the levitation force together with ...
