Abstract:

In recent years, it was found that antiperovskite manganese nitrides, with the giant and isotropic negative thermal expansion, show the controllable coefficient and temperature range of negative thermal expansion. Their abundant physical properties, such as magnetostriction, magnetovolume effect, thermal and electrical conduction, and near zero temperature coefficient of resistance, etc, have aroused great interest. The thorough study of crystal structure, negative thermal expansion, mechanism and physical properties of antiperovskite manganese nitrides is significant for essential understanding and potential application. In this review, the development of negative thermal expansion materials especially on manganese nitrides is briefly introduced. The state of the art of studying antiperovskite manganese nitrides are summarized and commented, including classification, negative thermal expansion mechanism, and physical and mechanical properties. The problems and prospects for antiperovskite manganese nitrides with negative thermal expansion materials are described.
