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…

Dual thermal pseudocritical features in a spin-1/2 Ising chain with twin-diamond geometry
Onofre Rojas
We study the coupled twin-diamond chain, a decorated one-dimensional Ising model motivated by the magnetic structure of . By a…

Spectral mechanism and nearly reducible transfer matrices for pseudotransitions in one-dimensional systems
Onofre Rojas
While true phase transitions are forbidden in one-dimensional systems with short-range interactions, several models have recently been shown to exhibit sharp yet analytic thermodyn…
