Structural and magnetic study of a dilute magnetic semiconductor: Fe doped CeO2 nanoparticles
Shalendra Kumar, Geun Woo Kim, B. H. Koo +3
This paper reports the effect of Fe doping on the structure and room temperature ferromagnetism of CeO2 nanoparticles. X-ray diffraction and selective area electron diffraction mea…
Electron Dynamics in Films Made of Transition Metal Nanograins Embedded in SiO2:Infrared Reflectivity and Nanoplasma Infrared Resonance
Nestor E. Massa, Juliano C. Denardin, Leandro M. Socolovsky +2
We report on near normal infrared reflectivity spectra of ~550 nm thick films made of cosputtered transition metal nanograins and SiO2 in a wide range of metal fractions. Co0.85(Si…
Giant magnetoimpedance in crystalline Mumetal
H. B. Nie, A. B. Pakhomov, X. Yan +2
We studied giant magnetoimpedance (GMI) effect in commercial crystalline Mumetal, with the emphasis to sample thickness dependence and annealing effects. By using appropriate heat…
Giant AC magnetoresistance and anisotropic AC magnetoresistance in granular magnetic alloys
A. B. Pakhomov, J. C. Denardin, M. Knobel +1
(withdrawn)AC resistance of melt-spun granular magnetic Cu85Co15 ribbons was measured as a function of temperature in the range 5-300 K, magnetic field Hdc in the range -60 kOe to…
Anomaly of AC resistance in magnetic nanoparticle alloys at spin-glass-like transition
A. B. Pakhomov, J. C. Denardin, M. Knobel +1
(withdrawn) A combined study of magnetic susceptibility and AC resistance was performed on melt-spun Cu-Co granular magnetic ribbons. The AC resistance as a function of temperature…
