Calculation of the vapor pressure of a magnetic material in the presence of an external magnetic field

Abstract

One kind of physical phenomenon connected to magnetic fields is magnetism. Temperature, pressure, and the applied magnetic field all affect a material's magnetic state, and as these factors vary, a material may display multiple forms of magnetism. As these factors vary, a material may display multiple types of magnetism. In ordinary life, paramagnetic, diamagnetic, and antiferromagnetic materials are sometimes referred to as non-magnetic since the force of a magnet on them is typically too faint to be felt and can only be detected by laboratory equipment. The magnetic moments of atoms orbiting electrons are the primary cause of a material's magnetic characteristics. When it comes to the magnetization of materials, the magnetic moments of atoms' nuclei are usually thousands of times lower than those of electrons. In some situations, however, nuclear magnetic moments are crucial, especially in nuclear magnetic resonance and magnetic resonance imaging.The enormous number of electrons in a material are arranged such that their magnetic moments cancel out. In this paper, we obtain an analytical expression for the vapor pressure of a paramagnetic solid for high temperatures. We have considered the behavior of magnetic materials in the presence of an external magnetic field using the thermodynamical analysis and the elements of statistical mechanics in microscopic systems. We found that the vapor pressure depends on the magnetic susceptibility of material and the external field applied.
