Comparative study of the magnetic stiffness, levitation and guidance force properties of single and multi seeded YBCOs for different HTS-PMG arrangements
Ozturk K.; Sahin E.; Abdioglu M.; Kabaer M.; Celik S.; Yanmaz E.; Kucukomeroglu T. (Elsevier Ltd, 2015)Abstract It is crucial to improve the magnetic levitation, guidance and stiffness performances of the HTS Maglev systems for real-scale applications. In this study, the magnetic levitation force, guidance force and magnetic ... -
Comparison of Levitation Forces of Bulk MgB2 Superconductors Produced by Nano Boron and Carbon-Doped Nano Boron
Duz I.; Guner S.B.; Erdem O.; Demir I.; Kapucu V.; Çelik Ş.; Ozturk K.; Hossain S.; Gencer A.; Yanmaz E. (Springer New York LLC, 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 Er doping on the superconducting properties of porous MgB2
MgB2 bulk sample with porous structure was produced by using the in-situ solid-state reaction method under argon (Ar) atmosphere of 10 bar. Elemental Er in powder form was doped into MgB2 with different compositions ... -
Effect of laser irradiation on activation energy, irreversibility field and upper critical magnetic field of bulk MgB2 superconductor
In this study, the role of laser irradiation on the upper critical field (Hc2), the irreversibility field (Hirr) and the activation energy (U0) of bulk MgB2 superconductor was first time investigated with the aid of ... -
Effect of laser irradiation on superconducting properties of bulk MgB2 sintered at different temperatures
The surfaces of MgB2 bulk samples produced by a pellet/closed tube method at two different sintering temperatures of 650 and 850 °C, after hot pressing at 200 °C, were irradiated with the same irradiation dose by using an ... -
Effect of magnetic flux distribution and magnetic powder addition on the magnetic levitation force of Sm123 superconductors
Abdioglu M.; Ozturk K.; Kutuk S.; Bolat S.; Yanmaz E. (2012)Sm123 and Sm211 were prepared by melt-powder-melt-growth and solid-state-reaction techniques, respectively, to have the nominal composition of (Sm123) 0.75 (Sm211) 0.25. After the preparation of this composition, the Fe-B ... -
Effects of initial cooling conditions and measurement heights on the levitation performance of bulk MgB2 superconductor at different measurement temperatures
Erdem O.; Ozturk K.; Guner S.B.; Celik S.; Yanmaz E. (Springer New York LLC, 2014)The levitation properties of MgB2 prepared by hot press at 200 ° C and then pellet/closed tube method has been investigated. The vertical and lateral levitation forces (Fz and Fx) on a cylindrical NdFeB permanent magnet ... -
Enhanced Pinning Properties of Laser-Irradiated Bulk MgB2 Superconductors
In order to investigate the effect of laser irradiation on the superconducting properties of MgB2, a pellet-shaped sample was produced and cut into two pieces. The dot-shaped molten patterns, with the distance of 100 µm ...
