Dependence of the magnetization and remanence of single-domain particles on the second cubic anisotropy constant
(2001) [Artigo de periódico]Magnetization and remanent magnetization curves for noninteracting single-domain particles with cubic magnetocrystalline anisotropy have been calculated, taking into account the first two anisotropy constants. The dependencies ... -
Emergence of junction dynamics in a strongly interacting Bose mixture
(2018) [Artigo de periódico]Westudy the dynamics of a one-dimensional system composed of a bosonic background and one impurity in single- and double-well trapping geometries. In the limit of strong interactions, this system can be modeled by a spin ... -
Energy-lowering and constant-energy spin flips : emergence of the percolating cluster in the kinetic Ising model
(2022) [Artigo de periódico]After a sudden quench from the disordered high-temperature T0 → ∞ phase to a final temperature well below the critical point TF Tc, the nonconserved order parameter dynamics of the two-dimensional ferromagnetic Ising model ... -
Generation of spin currents by a temperature gradient in a two-terminal device
(2021) [Artigo de periódico]Theoretical and experimental studies of the interaction between spins and temperature are vital for the development of spin caloritronics, as they dictate the design of future devices. In this work, we propose a two-terminal ... -
Role of spin-transfer torques on synchronization and resonance phenomena in stochastic magnetic oscillators
(2016) [Artigo de periódico]A theoretical study on how synchronization and resonance-like phenomena in superparamagnetic tunnel junctions can be driven by spin-transfer torques is presented. We examine the magnetization of a superparamagnetic free ... -
Slicing the three-dimensional Ising model : critical equilibrium and coarsening dynamics
(2015) [Artigo de periódico]We study the evolution of spin clusters on two-dimensional slices of the three-dimensional Ising model in contact with a heat bath after a sudden quench to a subcritical temperature. We analyze the evolution of some simple ...
