Journal ArticleDOI
Evaluation of the linear magnetostriction in amorphous wires using the giant magneto-impedance effect
TL;DR: In this article, the stress dependence of the magneto-impedance effect is explored to estimate the magnetostriction constant and its stress derivative on a nearly non-magnetostrictive Co 68.1 Fe 4.4 Si 12.5 B 15 amorphous wire.
Journal ArticleDOI
Structural and magnetic properties of chemically synthesized Fe doped ZnO
Shalendra Kumar,Young Joo Kim,Bon Heun Koo,Surender K. Sharma,Jose M. Vargas,Marcelo Knobel,Sanjeev Gautam,Keun Hwa Chae,Do Kyun Kim,Young Keun Kim,C. G. Lee +10 more
TL;DR: In this paper, the synthesis of Fe-doped ZnO with nominal composition of Zn0.99Fe0.01O by using a coprecipitation method was reported.
Journal ArticleDOI
Frequency dependence of the magnetoimpedance in amorphous CoP electrodeposited layers
J.P. Sinnecker,Marcelo Knobel,Kleber R. Pirota,Jorge M. Garcia,Agustina Asenjo,Manuel Vázquez +5 more
TL;DR: In this paper, the magnetic properties and changes of impedance upon external field (MI) were studied in amorphous CoP magnetic layers obtained by galvanostatic electrodeposition over cylindrical Cu substrates.
Journal ArticleDOI
Effects of magnetic interparticle coupling on the blocking temperature of ferromagnetic nanoparticle arrays
Marcelo Knobel,Wallace C. Nunes,Herbert Winnischofer,Tulio C. R. Rocha,Leandro M. Socolovsky,C.L. Mayorga,Daniela Zanchet +6 more
TL;DR: In this article, the influence of magnetic interparticle coupling on the superparamagnetic relaxation behavior was investigated by means of DC magnetization measurements, and a phenomenological model based on the random anisotropy and micromagnetic theories was presented.
Journal ArticleDOI
Effect of zinc concentration on the magnetic properties of cobalt-zinc nanoferrite
Ritu Rani,Surender K. Sharma,Surender K. Sharma,Kleber R. Pirota,Marcelo Knobel,Sangeeta Thakur,Mahavir Singh +6 more
TL;DR: In this article, a solution combustion method was used to extract nano-cobalt-zinc ferrite (CZFO) Co (1-x)Zn xFe 2O 4 with varied quantities of zinc.
