Thermodynamic and magnetocaloric properties of a triangular spin-1/2 cluster with Dzyaloshinskii-Moriya interaction
Jordana Torrico, Romulo A. Silva, S. M. de Souza +1
We present a theoretical investigation of the magnetic and thermodynamic properties of the triangular spin-1/2 cluster with Dzyaloshinskii-Moriya (DM) interaction, described by a s…
Unusual low-temperature behavior in the half-filled band of the one-dimensional extended Hubbard model in atomic limit
Onofre Rojas, S. M. de Souza, J. Torrico +4
Recently, a kind of finite-temperature pseudo-transition was observed in several quasi-one-dimensional models. In this work, we consider a genuine one-dimensional extended Hubbard…
Magnetocaloric effect in -type compounds using the Heisenberg antiferromagnetic model in a triangular ring
G. A. Antonio, J. Torrico, A. S. da Mata +2
In this work we present a theoretical investigation into an antiferromagnetically coupled spin system, specifically (), which exhibits an isoscel…
Study of the ground state and thermodynamic properties of Cu5-NIPA-like molecular nanomagnets
J. Torrico, J. A. Plascak
The thermodynamic properties of a spatially anisotropic spin-1/2 Heisenberg model for a Cu pentameric molecule is studied through exact diagonalization. The elementary geometry…
Low temperature pseudo-phase transition in an extended Hubbard diamond chain
Onofre Rojas, Jordana Torrico, L. M. Veríssimo +3
We consider the extended Hubbard diamond chain with an arbitrary number of particles driven by chemical potential. The interaction between dimer diamond chain and nodal couplings i…
Magnetoelastic properties of a spin-1/2 Ising-Heisenberg diamond chain in vicinity of a triple coexistence point
N. Ferreira, J. Torrico, S. M. de Souza +2
We study magnetoelastic properties of a spin-1/2 Ising-Heisenberg diamond chain, whose elementary unit cell consists of two decorating Heisenberg spins and one nodal Ising spin. It…
