Abstract
The magnetism is a type of physical phenomena associated with magnetic fields. The magnetic state of a material depends on temperature and other variables such as pressure and the applied magnetic field and a material may exhibit more than one form of magnetism as these variables change. A material may exhibit more than one form of magnetism as these variables change. The force of a magnet on paramagnetic, diamagnetic, and antiferromagnetic materials is usually too weak to be felt, and can be detected only by laboratory instruments, so in everyday life these substances are often described as non-magnetic. The magnetic properties of materials are mainly due to the magnetic moments of their atoms orbiting electrons. The magnetic moments of the nuclei of atoms are typically thousands of times smaller than the electrons magnetic moments, so they are negligible in the context of the magnetization of materials. Nuclear magnetic moments are nevertheless very important in other contexts, particularly 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.
