For this reason, in this work, a study of the exchange bias effect present in La2-3Ca1-3MnO3-La1-3Ca2-3MnO3.
This study was carried out by using the Monte Carlo method and the Metropolis Algorithm.
In order to make easy this study, a graphic user interface was built alloying a friendly interaction.
The interface permits to control the thickness of Ferromagnetic and Antiferromagnetic layer, temperatures the magnetic field, the number of Monte Carlo steps and the exchange parameters. Results obtained reflected the influence of all of these parameters on the exchange bias and coercive fields.
