Theory of the Scope Change under Magnetic Field, Temperature and Stress

Abstract

Mathematical model that describes connections between elastic and electromagnetic properties is pre-sented. These connections are based on possibility to change a volume of solid by temperature, pressure or magnetic field. New parameter of solid ”scope change”, that depends on elastic modulus, heat and thermal conductivity, thermal expansion, is proposed. The comparison of theoretical and experimental results was made for conductivity data of LaMnO3.
