Effect of magnetic ordering on the electronic structure of metals

TL;DR

This paper explores how magnetic ordering, such as ferromagnetism, influences the electronic structure of metals, including pseudogap formation and effects on electrical resistivity, with relations to magnetic energy and Curie temperature.

Contribution

It introduces a model linking magnetic ordering to pseudogap formation and electrical resistivity changes, providing relations between magnetic energy and Curie temperature.

Findings

Ferromagnetic ordering causes an energy pseudogap in metals.

The pseudogap type depends on the metal's band structure.

Magnetic ordering affects the temperature dependence of electrical resistivity.

Abstract

It is shown that ferromagnetic ordering in metals is associated with an opening of the energy pseudogap. This energy pseudogap belongs to a d-band type in d-metals and to an sp-band type in f-metals. A relation between the magnetic energy and the Curie temperature is obtained. Effect of magnetic ordering on the temperature dependence of the electrical resistivity is considered.
