Structure and magnetic properties of oxygen-stabilized tetragonal Ni nanoparticles prepared by borohydride reduction method
TL;DR: In this paper, a comprehensive study on the structure and magnetic properties of ultrafine Ni nanoparticles prepared by the borohydride reduction method has been performed, where a spontaneous surface oxide layer of NiO encapsulates the Ni particles, as these have been prepared under ambient atmosphere.

Spin-glass-like behavior in mechanically alloyed nanocrystalline Fe-Al-Cu
J. A. De Toro,M. A. López de la Torre,J. M. Riveiro,R. Saez Puche,A. Gómez-Herrero,L.C. Otero-Díaz +5 more
TL;DR: In this paper, the magnetic properties of mechanically alloyed materials have been investigated and it was shown that the irreversibility between the field-cooled and zero-fieldcooled magnetization curves closely resemble those exhibited by spin glasses.

Exchange bias and nanoparticle magnetic stability in Co-CoO composites
TL;DR: In this article, a series of Co{sub x}(CoO){sub 1-x} thin films have been synthesized by sputtering Co in an oxygen atmosphere using different rf sputtering powers as a means to vary the concentration x.

Accurate interferometric measurement of electro-optic coefficients: application to quasi-stoichiometric LiNbO3
TL;DR: In this article, a modulation interferometric technique for accurate measurement of electro-optic coefficients is presented by detecting the signal both at first and second harmonics of the modulation frequency, while the phase is electronically scanned along two interference orders.

Effect of interstitial oxygen on the crystal structure and magnetic properties of Ni nanoparticles
TL;DR: The structure and magnetic properties of fine Ni nanoparticles (∼65nm diameter) having a spontaneous surface oxide layer have been studied in this article, where the particles were prepared by the chemical reduction of nickel ions in an aqueous medium, with sodium borohydride as the reducing agent X-ray diffraction (XRD), transmission electron microscopy, and magnetization measurements (M-H plots and field cooled∕zero field cooled curves) have been used for characterizing the samples No detectable change is observed in the M-H curves or in the X
