Magnetic Order in NbS Nanoribbons
(Institute of Electrical and Electronics Engineers, 2013-07)
Transition metal dichalcogenides are well known for their laminar structure, similar to that of graphite. The bulk structure of many of them has been the subject of several studies during the last 30 years, due to their ...
Evidence of defect-mediated magnetic coupling on hydrogenated Co-doped ZnO
(2013-04-05)
Hydrogenated bulk Zn1-xCoxO samples were synthesized via standard solid-state reaction route with Co molar concentrations up to 15 at.%. Magnetic characterization demonstrates a room temperature ferromagnetic behavior ...

Two-dimensional Ising model with Einstein site phonons
(American Physical Society, 2019-04-23)
We consider a simple Ising magnetic model in two dimensions with Einstein site phonons and study it using Monte Carlo simulations that take into account both degrees of freedom simultaneously. In nonfrustrated systems, ...
Synthesis and characterization of magnetic cross-linked enzyme aggregate and its evaluation of the alternating magnetic field (AMF) effects in the catalytic activity
(2020-12-15)
A magnetic cross-linked enzyme aggregate (MCLEA) of cellulases and a non-magnetic analogue (CLEA) were synthesized and further investigated. The obtained MCLEA and CLEA showed a high enzyme loading efficiency of 90% and ...
On the determination of the magnetic entropy change in materials with first-order transitions
(Elsevier Science BvAmsterdamHolanda, 2009)
Cation distribution and magnetic characterization of the multiferroic cobalt manganese Co2MnO4 spinel doped with bismuth
(2013-03-01)
The structural and magnetic properties of the cubic spinel oxide Co 2MnO4 (Fd3m space group) doped with different concentrations of bismuth, were investigated by X-ray diffraction and SQUID magnetometry. The Bi3+ ions ...
