Postdoctoral Researcher Advanced Modeling for Spintronic Devices and Systems
What you will do
In spintronics, the transfer of intrinsic electron spin by means of spin transfer torque or spin orbit torque is central to manipulating the magnetization state of magnetic materials. We need to understand and engineer the manipulation of the magnetization state in a magnetic layer for generating, detecting and manipulating (phase shifting and amplifying) spin waves or magnetization waves. This is key to develop spin wave logic for future low power devices. In addition, we consider using the magnetoelectric effect for low power voltage controlled generation and detection of spin waves or other magnetic excitations.
The search for enhanced spin orbit torque acting on the magnetization state of magnetic materials is also crucial for efficient low-energy magnetization switching. Heavy metals such as Pt and Ta are currently being investigated as strong spin-orbit interaction materials giving rise to spin Hall effect or the Rashba-Edelstein effect.
The main goals of this project are:
- Model and understand the microscopic quantum mechanics behind the generation of spin orbit torques through the Spin Hall, Rashbah-Edelstein or Dresselhaus effect.
- Incorporate the resulting magnetization dynamics in a micromagnetic simulation tool such as OOMMF.
- Develop advanced modelling capabilities to describe the magnetoelectric effect using a multiphysics approach. In this approach, magnetization dynamics will be linked to material parameters such as stress/strain tensors giving rise to magnetostrictive effects in magnetoelectric elements.
Key focus points:
- Magnetization dynamics in magnetic materials and layers interacting with heavy metals or topological insulators for enhanced spin-orbit torque
- Spin wave propagation, generation and detection
- Enhanced magnetization switching in memory devices
- Magnetoelectric device physics and modelling
