My material composition has high saturation magnetism compared to other reported papers of the same composition. What are all the factors that determine saturation magnetism?
The saturation magnetization of a material is influenced by several factors, including:
Atomic structure and composition: The atomic structure of a material determines its magnetic properties. Materials with unpaired electrons in their atomic structure, such as iron, cobalt, and nickel, exhibit high magnetic properties.
Crystal structure: The crystal structure of a material can influence its magnetic properties. Some crystal structures can result in the alignment of magnetic moments, leading to a high saturation magnetization.
Magnetic anisotropy: The direction in which a material is magnetized can influence its magnetic properties. Magnetic anisotropy is the tendency of a material to exhibit different magnetic properties in different directions. Materials with high magnetic anisotropy exhibit high saturation magnetization.
Impurities and defects: Impurities and defects in a material can affect its magnetic properties. Even small amounts of impurities or defects can significantly reduce the saturation magnetization of a material.
Temperature: Temperature can affect the magnetic properties of a material. At high temperatures, the thermal energy can disrupt the alignment of magnetic moments, leading to a decrease in saturation magnetization.
Magnetic field strength: The strength of the magnetic field applied to a material can affect its magnetic properties. A stronger magnetic field can result in a higher saturation magnetization.
Therefore, it is important to carefully control the processing and synthesis conditions to optimize the magnetic properties of a material.
I agree with the previous answers. There are simply too many factors affecting the magnetic properties of a material. Slightly different thickness, linear dimensions, or additional defects can lead to significant changes in the saturation magnetization and coercive field. The first thing I would suggest checking is the sample's preparation method. Once I had a similar case with thin Py films that can have different coercive field depending on the chamber pressure in the magnetron sputtering setup.
