Electrical and Magnetic Characterization of BSCCO and YBCO HTS Tapes for Fault Current Limiter Application
(Institute of Electrical and Electronics Engineers (IEEE), 2011-06-01)
Several high temperature superconductor (HTS) tapes have been developed since the late eighties. Due to the new techniques applied for their production, HTS tapes are becoming feasible and practical for many applications. ...
Separating the influence of electric charges in magnetic force microscopy images of inhomogeneous metal samples
(2018-01-15)
In this study, we investigate artifacts arising from electric charges present in magnetic force microscopy images. Therefore, we use two austenitic steel samples with different microstructural conditions. Furthermore, we ...
Magnetic properties of acicular ultrafine iron particles
(Institute of Electrical and Electronics Engineers (IEEE), 2002-09-01)
Magnetic properties of acicular (similar to60 and similar to200 nm) iron particles, obtained by reduction of alumina-coated goethite particles, are reported. X-ray diffraction and Mossbauer spectroscopy showed that the ...
Effect of structural anisotropy on electrical and magnetic properties of polyaniline conducting films
(2013-03-12)
It is shown that highly conducting films of polyaniline protonated with di-esters of sulfosuccinic and sulfophthalic acids which contain alkyl- or alkoxy-type substituents exhibit highly anisotropic structural, electrical ...
Electrical transport in disordered and ordered magnetic domains under pressures and magnetic fields
(IOP PUBLISHING LTD, 2009)
Magnetic M( T, H, P) and electrical transport.( T, H, P) measurements in a strong spin-lattice-charge coupled La(0.7)Ca(0.3)MnO(3) system have been conducted. The application of H and P leads to the formation of different ...

Effects of the Compaction Pressure on the Magnetic Properties of a Sintered Fe-Based Alloy
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
The structural and magnetic properties of a Fe-based alloy before and after sintering have been analyzed. X ray diffraction measurements confirm the deformation of the magnetic particles in the compacted samples. After ...
