Dip effect in ac susceptibility due to surface barrier with flux creep

Detection of the flux creep regime in the AC susceptibility curves by using higher harmonic response

In order to investigate the dynamic properties of the flux line lattice, the temperature dependencies of the basic and Ž . higher harmonic complex AC susceptibilities have been analysed. In particular, the first i.e., fundamental and the third Ž . X Ž . Y Ž . harmonic x T sx T q ix T , have been measured at different frequencies, and the measurements have been 1,3 1,3 1,3 compared with both ana...

Flux creep and flux jumping.

The flux jump instability of Bean’s critical state in the flux-creep regime of type-II superconductors is considered. We find the flux-jump field B j which determines stability criterion of the superconducting state. The dependence of B j on the external magnetic-field ramp rate Ḃe is calculated. We demonstrate that under the conditions typical for most of the magnetization experiments the slop...

Micropolar Fluid Flow Induced due to a Stretching Sheet with Heat Source/Sink and Surface Heat Flux Boundary Condition Effects

Computational and mathematical models provide an important compliment to experimental studies in the development of solar energy engineering in case of electro-conductive magnetic micropolar polymers. Inspired by further understanding the complex fluid dynamics of these processes, we examine herein the non-linear steady, hydromagnetic micropolar flow with radiation and heat source/sink effects ...
