Laboratory of Novel Magnetic Materials

General information

The Laboratory of Novel Magnetic Materials was established in June 2013. The Laboratory is headed by Dr. Valeria Rodionovf (valeriarodionova@gmail.com)

The research staff and graduate students are actively involved in both research and education activities. Researchers of the Laboratiry initiated and organized the first interdisciplinary international conference in Russia (http://lnmm.ru/ibcm_2015/) – “International Baltic Conference on Magnetism: focus on biomedical aspects”.

Scientists from different countries often visit the Immanuel Kant Baltic Federal University and the Laboratory to discuss the latest breakthroughs in the development, creation and study of new materials, the use of advanced magnetic materials as well as new methods in biomedicine. The Laboratory researchers often present the results of their work at international conferences. They are frequently invited as keynote and guest speakers to numerous international conferences. They publish articles in reviewed journals indexed in Scopus and the Web of Science.

Current research projects:

  1. Development of physical principles of creating a magnetic manipulator based on partially coated two-phase magnetic microwires (partly funded by a state grant (2014-2016), and partly by the RFBR)

  2. Development of a magnetic field sensor based on the magnetoplasmons crystal (funded by the RFBR)
