Yıldız, Şükrü; İnanır, Fedai; Kölemen, Uğur (Elsevier, 2010)Influence of the Meissner current on the field-induced variations of the microwave (mw) surface resistance in type-II superconductors is demonstrated to be well reproduced by exploiting different critical state models. ... -
An extended model for coexistence of superconductivity and paramagnetism in high-Tc superconductors
İnanır, Fedai (2008)In the present work, the total magnetization in superconducting state is separated into critical state and paramagnetic components in terms of an H(x)-dependent magnetic flux density. Utilizing this model, we reproduce ... -
Influences of ferromagnetic deflectors between layers of superconducting power transmission cables on transport current losses
Çiçek, Ahmet; İnanır, Fedai (Springer International Publishing, 2014)Alternating-current losses in two-layer power transmission cables constructed by type-II superconducting strips in the presence of ferromagnetic deflectors between the layers are numerically investigated. Each layer comprises ... -
Magnetization of Gd diffused YBa2Cu3O7-x superconductor: experiment and theory
İnanır, Fedai; Yıldız, Şebnem; Öztürk, Kemal; Çelebi, Selahattin (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 ... -

A theoretical study for temperature dependence of levitation force of high-T-c superconductors
İnanır, Fedai; Yıldız, Şükrü; Okutan, Mustafa; Kölemen, Uğur (Elsevier, 2013)The temperature effect on the levitation force of a cylindrical type-II superconductor was investigated theoretically by solving the critical state equation. Analytical expressions are obtained for the levitation force ... -
The viscous flux-flow effect on the pinning induced magnetostriction of type-II superconductors
We have investigated the magnetostriction of type II superconductors under the viscous flux-flow. The critical state approach was employed to obtain the magnetostriction loops versus applied field. The flux profile equations ...
