BARCO-RIOS, H.; ROJAS-CALDERON, E.  e  RESTREPO-PARRA, E.. GRAPHICAL INTERFACE AS A TOOL IN SIMULATION OF MAGNETIC PROPERTIES OF Re_2/3A_1/3MnO₃ MANGANITES WITH MONTE CARLO METHOD AND HEISENBERG MODEL. Rev. ing. univ. Medellín [online]. 2013, vol.12, n.22, pp.181-192. ISSN 1692-3324.

The graphics interface is useful in specifying and examining chemical structures and physical properties. In this scientific and technological research paper, the SIMMON (MMSP - Manganite magnetic simulation properties) software is presented, as a visualization program, that allows to observe, the magnetization, susceptibility, energy, specific heat, the hysteresis loops and the resistivity of magnetic materials. This properties can be obtained from the simulation of different manganites Re_2/3A_1/3MnO₃, where Re is a rare earth metal ions as La, Nd and Pr with valence 3+, which are bonded with Mn³⁺-3d4 ions and A is a 2+ alkaline earth ion such as Ba, Ca, Sr, among others, bonded with Mn⁴⁺-3d3. The based method for the simulations is Monte Carlo combined with Metropolis algorithm and Heisenberg model.

Palavras-chave : Manganites; magnetization; hysteresis; resistivity; Monte Carlo.
