The course involves the study of the current state of rapidly developing areas of physics and
technology related to the magnetism of nano and microsystems. On the one hand, modern
methods for studying nanostructures will be discussed, including synchrotron and X-ray
spectroscopy, neutron scattering, tunneling microscopy, etc., and on the other hand, it is
planned to study theoretical approaches used to describe physical properties, the ordering and

dynamics of magnetic nanosystems as well as for the interpretation of experimental data. It is
also planned to implement individual projects related to the modeling of magnetic micro and
nanosystems.

Additional Information

Наряду изучением материала на лекциях предполагается выполнение индивидуальных
проектов, включающих компьютерное моделирование, аналитические и численные
расчеты, а также доклады-презентации с представлением результатов. На финальную
оценку влияют как результат экзамена, так и результаты работы по проектам.
