Abstract:
The utilization of magnetic elements and spin current in spintronics devices enables the development of computer magnetic random access memories. The use of spin as a tool for information writing and reading makes it possible to obtain devices that switch faster, with lower energy consumption, significantly reduced Joule heating and being non-volatile at the same time. To realize this idea we focuse on devices based on oxide materials, in particular on the multiferroic tunnel junctions (MFTJ) with an addition of a spin-orbit coupling material. Such MFTJ can be operated by a current flowing only through the upper electrode utilizing spin Hall effect (SHE) and spin orbit torque (SOT). The subject we propose relates to recently observed interesting phenomena (with a high application potential) like a possibility of tunning SOT with the ferroelectric polarization of the ferroelectric tunneling barrier.
Research facilities:
The experimental work we propose will be carried out in the pulse-laser deposition, cleanroom and other laboratories of Academic Centre for Materials and Nanotechnology at our University.
