Theoretical determination of Ising-type transition by using the Self-Consistent Harmonic Approximation
A. R. Moura
Over the years, the Self-Consistent Harmonic Approximation (SCHA) has been successfully utilized to determine the transition temperature of many different magnetic models, particul…
Theoretical analysis of FMR-driven spin pumping current and its properties via Self-Consistent Harmonic Approximation
A. R. Moura
We applied the Self-Consistent Harmonic Approximation (SCHA), combined with coherent states formalism, to study the ferromagnetic resonance (FMR) in a ferromagentic/normal metal ju…
Effectiveness of the Self-Consistent Harmonic Approximation in ferromagnets with dipolar interactions
A. R. Moura
Among the various methods for treating magnetic models, the Self-Consistent Harmonic Approximation (SCHA) has successfully described ferro and antiferromagnetism in many different…
Spin coherence on the ferromagnetic spherical surface
A. R. Moura
Spintronics on flat surfaces has been studied over the years, and the scenario is relatively well-known; however, there is a lack of information when we consider non-flat surfaces.…
Spin current injection at magnetic insulator/superconductor interfaces
Vinícius S. U. A. Vargas, Antônio R. Moura
Opposite to the common idea of a magnetic order requirement to obtain spin current propagation, materials with no magnetic ordering have also been revealed to be efficient spin con…
Phase transitions in the two-dimensional single-ion anisotropic ferromagnetic with long-range interactions
A. R. Moura
In the present work, we investigate the effects of long-range interactions on the phase transitions of two-dimensional ferromagnetic models with single-ion anisotropy at zero and f…
