Determination of the blocking temperature of magnetic nanoparticles: The good, the bad, and the ugly
(American Institute of Physics, 2015-11-13)
A numerically solved two-level Stoner-Wohlfarth model with thermal agitation is used to simulate Zero Field Cooling (ZFC)-Field Cooling (FC) curves of monosize and polysize samples and to determine the best method for ...
Magnetic properties of cobalt ferrite octahedrons obtained from calcination of granular nanotubes growing on bacterial nanocellulose
(Elsevier Science, 2019-09)
We present an in-depth magnetic study of polycrystalline, microstain-free, magnetic, and thermally stable cobalt ferrite (CoFe2O4) octahedrons with an edge dimension of 214 nm. Nanoparticles were synthesized from granular ...

Magnetic behavior of iron-modified MCM-41 correlated with clustering processes from the wet impregnation method
(Elsevier Science, 2016-03)
Magnetic MCM-41 type mesoporous silica materials were synthetized and modified with different iron loadings by the wet impregnation method. The evolution of iron speciation, depending on the metal loading and associated ...
Caracterização magnética de compósitos multiferróicos particulados Pb(Zr0,52Ti0,48)O4/CoFe2O4
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2014-08-26)
This work was studied the magnetic and electrical properties of particulate multiferroic composite Pb (Zr0,52Ti0,48) O4 / CoFe2O4 (PZT / CFO) (0-3 type) prepared by the polymeric method of Pechini and sintered by ultra-rapid ...
Subórdenes lineales κ-densos de los números reales
(Universidad Michoacana de San Nicolás de Hidalgo. Universidad Nacional Autónoma de México, 2015-07)
In one of the earliest results related to the abstract structure of linear orders, G. Cantor proves that any of the linear orders dense numerable isomorphic son. One question is natural and the same conclusion remains valid ...
