Functional Magnetic Materials
The magnetic anisotropy in effective magnetic materials, which surfaces from the arrangement of magnetic moments under external field, can be developed at different structural scales. Magnetic patterning, magnetic ordering, and text ration are at the beginning of this anisotropy development. Present improved superconducting magnet technology allows higher field intensities to be produced more easily and enables researchers to gather evidence on magnetic field effects that were formerly thought to be negligible. The magneto-thermodynamic effect is one of them and includes the magnetization energy as an extra parameter to modify microstructures. Control of functional properties can thus result from magnetic monitoring of the phase transformation, and kinetics can be impacted by the magnetic energy contribution.
The molecule-based magnet is a kind of magnetic material. The physical building blocks in molecule-based magnets are molecular in nature. These building blocks are either organic molecules and coordination compounds or a combination of both. In this case, the unpaired electrons may exist in d or f orbitals on isolated metal atoms, but may also exist in localized p and s orbitals as well as the purely organic classes. They may be categorized as hard or soft, like conventional magnets and dependent on the magnitude of the coercive field. An additional distinguishing feature is that molecule-based magnets are arranged via low-temperature solution-based techniques, versus high-temperature metallurgical processing or electroplating. This permits a chemical tailoring of the molecular building blocks to modify the magnetic properties.
