Effect of composition and short-range order on the magnetic moments of Fe in Fe/sub 1-x/V/sub x/ alloys
(2000) [Artigo de periódico]We report dc magnetization, Mössbauer spectroscopy, and x-ray-diffraction measurements on Fe₁₋xVx alloys, quenched or heat treated, with single phase bcc structure in the whole concetration range. It is well known that the ... -
Exchange bias in a ferromagnet/antiferromagnet system with TCTN
(2011) [Artigo de periódico]This paper reports experimental results obtained on an unconventional exchange bias (EB) system where the ferromagnetic layer, Ni0.75Cu0.25, has lower ordering temperature (TC) than that (TN) of the antiferromagnetic one, ... -
Fenomenologia crítica e correntes AC nos sistemas magnéticos reentrantes σ-Fe-C, σ-Fe-V e Au-Fe
(2011) [Tese]Este trabalho consiste de um estudo da fenomenologia crítica nas vizinhanças da temperatura de Curie (TC) das ligas binárias reentrantes s-Fe1-xCrx, onde x = 0,46 e 0,49; s-Fe0,52V0,48 e Au1-yFey, onde y = 0,135; 0,15; ... -

Suppression of magnetic ordering in quasi-one-dimensional FexCo1−xNb2O6 compounds
(2011) [Artigo de periódico]We present a systematic investigation of the series of compounds FexCo1−xNb2O6 by means of x-ray and neutron powder diffraction combined with magnetic measurements, carried out in the paramagnetic as well as in the ordered ...
