Elena Zhuravleva, a student at the Faculty of Radiophysics, explores composite materials and plans to establish a means of recording and reading information based on them that can replace the existing hard drives in computers.
Elena is studying multiferroics. Their electrical properties can be controlled by the magnetic field and the magnetic properties – by electrical field. Because of this physical effect, a new memory device with higher density of information using much less energy can be created based on multiferroics.
The student explains that it will also solve the problem of cooling by combining hard disk drives into an array to store large amounts of information. Now bulky radiators are used to cool the system. By reducing heat emission, new memory devices do not require radiators or other cooling systems.
At the moment, scientists are already using the TSU multiferroics as materials that convert electromagnetic radiation energy into heat. This is used in radioelectronics devices for electromagnetic compatibility, protection of biological objects of electromagnetic radiation, and to create an anechoic chamber.
