Electronic structure and magnetic properties of FeWO 4 nanocrystals synthesized by the microwave-hydrothermal method
(2012-11-01)
This communication reports that FeWO 4 nanocrystals were successfully synthesized by the microwave-hydrothermal method at 443 K for 1 h. The structure and shape of these nanocrystals were characterized by X-ray diffraction, ...
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 ...
Evidence of defect-mediated magnetic coupling on hydrogenated Co-doped ZnO
(2013-04-05)
Hydrogenated bulk Zn1-xCoxO samples were synthesized via standard solid-state reaction route with Co molar concentrations up to 15 at.%. Magnetic characterization demonstrates a room temperature ferromagnetic behavior ...
Superconducting vortex fluctuations in YBa2Cu3O7-δ
(1996-01-20)
Measurements of magnetization in YBa2Cu3O7-δ single crystals were performed for applied fields H parallel and perpendicular to the ab planes. The data show a temperature T = T* at which the magnetization M(T*) is independent ...
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. ...
Relevant magnetic and soil parameters as potential indicators of the soil conservation status in Mediterranean agroecosystems
(Wiley, 2014-06)
The main sources of magnetic minerals in soils unaffected by anthropogenic pollution are iron oxides and hydroxides derived from parent materials through soil formation processes. Soil magnetic minerals can be used as ...
A new ultra-high-vacuum variable temperature and high-magnetic-field X-ray magnetic circular dichroism facility at LNLS
(Wiley-blackwell Publishing, IncMaldenEUA, 2009)
Magnetic studies and elemental analysis of river sediments: a case study from the Ponnaiyar River (Southeastern India)
(Springer, 2012-11)
The Ponnaiyar River is one of the largest rivers of the Tamil Nadu state (India), flowing a distance of 430 km from its point of origin to the sea. This work contributes with new data of magnetic and elemental composition ...

(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
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. ...
The exceptional Herbig Ae star HD 101412: The first detection of resolved magnetically split lines and the presence of chemical spots in a Herbig star
(Wiley Vch Verlag, 2010-04)
In our previous search for magnetic fields in Herbig Ae stars, we pointed out that HD 101412 possesses the strongest magnetic field among the Herbig Ae stars and hence is of special interest for follow-up studies of ...
