Multiferroic and smart materials Part 2

Scientific and technological progress in the main branches of technology is largely determined by the development of these studies and their introduction into high-tech production. Therefore, it is extremely important to present a correct idea about the unique class of magnetorheological materials. In this course…

About this course

 

Investigation of magnetic materials is one of the most important areas of modern physics, especially those areas of physics that are associated with the creation and prediction of the properties of new materials (including materials for nanotechnology). Magnetorheological materials are materials, which rheological (related to the processes of deformation and fluidity) properties can quickly and reversibly change when an external magnetic field is applied (viscosity, elasticity, plasticity extremely change in magnetic field). They belong to the so-called class of "smart" materials that react to changes in the environment and it physical or chemical properties. Within the course students should learn how to find out the main characteristics of magnetorheological materials, the technology of their production and research methods, the mechanisms of their properties formation, and the physical principles of the preparation of such materials.

During the course will be considered the next topics:
 

- Magnetorheological materials: types and applications
- Magnetic particles. Superparamagnetic particles. Magnetic properties of elastomers with low concentration. Langevin function.
- Elastomers. Mechanical properties. Piezoresistance and magnetoresistance. Magnetodielectric effect.

- Multiferroic properties of rheological materials.
