Abstract

The Hubbard model in its original form is used in the study of materials that present itinerant magnetismand is widely discussed in the scientific literature. However its form with more than a band presents asource of physical information that has not been more explored due to the increase of the complexity ofthe calculations. In this work we verify that the inclusion of one more band in the model increases theprecision for representing natural phenomena, making it thus more useful in the advance of thetechnology involving materials with itinerant magnetism.
