We introduce a Sherrington-Kirkpatrick spin-glass model with the addition of elastic degrees of freedom. The problem is formulated in terms of an effective four-spin Hamiltonian in the pressure ensemble, which can be treated ...

The magnetic and transport properties of the compound La0.7Sr0.3Mn1-xFexO3(0.1 ≤ x ≤ 0.4) have been studied by means of electrical resistivity, AC magnetic susceptibility, and DC magneti- zation. At low concentrations ...

Noble/transition bimetallic nanowires of nominal composition FexRh100-x (x = 15, 25, 54) are AC electrodeposited into 20 nm diameter hexagonally self-assembled nanopores of anodic alumina membranes. Nanowires about 18 nm ...

Magnetic properties of nanocrystalline NiFe(2)O(4) spinel mechanically processed for 350 h have been studied using temperature dependent from both zero-field and in-field (57)Fe Mossbauer spectrometry and magnetization ...

Materials belonging to the A2BWO6 and A2BVO6 families have shown interesting electrical and magnetic properties that may be applied to spintronics and fuel cell cathodes. The main motivation of this thesis is to synthesize ...

En el presente trabajo se adaptó un modelo tipo Ising vía método Monte Carlo dentro del estudio de las redes de coautoría dinámicas. Previamente, se realizó un análisis en el tiempo de las redes reales a partir del cual ...
