Schottky-Anormaly of the Ising Model on Kagomé Lattice in an External Magnetic Field

Abstract

The Schottky anomaly is one of the most universal phenomena in physical science and materials engineering. The Schottky anomaly is a prominent finite peak in the specific heat of materials at a low temperature, and it is the most important tool in understanding the unknown properties of new materials by using experimental techniques. Because kagome lattice has inherent frustration, the properties of materials on a kagome lattice are very profound, and it plays vital roles in studying new phenomena in science and engineering. Although both the Schottky anomaly and kagome lattice are important, the properties of the Schottky anomaly on a kagome lattice are not known. Here, we investigate the properties of the Schottky anomaly on a kagome lattice for the first time by using the Wang-Landau sampling method.
