Overview
The group covers all aspects of fundamental physics related to spin electronics by employing a wide range of theoretical approaches including ab initio, tight-binding, free electron and diffusive methods, combined with micromagnetic simulation approaches based on solution of Landau-Lifshitz-Gilbert (LLG) equation. This allows explaining experimental observations, providing solutions for specific problems and predicting novel properties and phenomena guiding the experimental work to optimize spintronic nanostructures.
Research directions
Electronic structure and magnetic properties of materials from first principles
Ab initio calculations based on DFT are performed in order to provide insights into fundamental mechanisms of various spintronic phenomena, and to propose novel materials and their efficient combinations with required electronic structure and magnetic properties for optimal performance of spintronic devices.
Spin-dependent transport theories
We employ tight-binding, free electron and diffusive approaches including Green function techniques in the framework of Keldysh and Kubo formalisms, in order to describe spin and charge transport properties in magnetic nanostructures with non-collinear magnetic moments in vertical, lateral and complex geometries.
Theoretical concepts for organic and graphene spintronics
The goal of this topic is to harvest theoretically novel spin-dependent properties (e.g. proximity effects and defect induced magnetism etc.) in organic, graphene and related 2D materials based structures in the context of emerging field of graphene spintronics.
Micromagnetic modeling
Magnetization dynamics (macrospin and micromagnetic) simulations under applied magnetic field and/or spin polarized currents are developed to address functionalities of spintronic devices (e.g. magnetization switching, synchronization and modulation for oscillators) in various geometries. Straightforward analytical models are developed to supplement fast and efficient understanding of the magnetization dynamics.
