Reply to the comment on the paper "Thermodynamics of two-dimensional magneto nanoparticles (P. Vargas, D. Altbir, M.Knobel and D. Laroze)" by H. Buettner and Yu. Gaididei
P. Vargas, D. Altbir, M. Knobel +1
It is shown that there is bi-stability in a two dimensional system consisting of non interacting magnetic nanoparticles with equal uniaxial anisotropies. It is also shown that bi-s…

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(withdrawn) A combined study of magnetic susceptibility and AC resistance was performed on melt-spun Cu-Co granular magnetic ribbons.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…
