This project focuses on Magnetic Random Access Memory, also known as MRAM. MRAM is a non-volatile memory technology that stores data using magnetic elements and is considered a promising candidate for future memory devices.

The aim of the project is to improve the understanding and efficiency of MRAM systems. This includes studying the relation between thermal stability and the write current needed to switch the memory state. The project uses existing simulation tools developed in the group, including energy barrier calculations and spintronic solvers.

Surface acoustic waves are generated by interdigital transducers on piezoelectric thin films and are used in applications such as radio-frequency filters and oscillators. Recent studies show that surface acoustic waves can interact with magnetic thin films placed on piezoelectric materials.

This Master’s project aims to extend micromagnetic simulation software to include magnetoelastic effects. The simulations will then be used to explore magnetic materials under magnetoelastic excitation. Depending on the student’s interests, the project can focus more on programming and modelling or more on physical simulations.

Supervisor: Claas Abert

This project investigates novel spintronic devices using micromagnetic simulations. The group has recently worked on a new type of spacer material for magnetic multilayers, which allows non-collinear coupling between two ferromagnetic layers with controlled coupling angles.

The aim of this Master’s project is to study how this material can be used in spintronic devices such as MRAM cells, spin-torque oscillators, and magnetic sensors.

Magnetic colloidal particles are relevant for magneto-controllable systems, for example in hyperthermia applications. To understand their behaviour, both the magnetisation dynamics inside the particles and their spatial rearrangement or self-assembly have to be considered.

In this Master’s project, molecular dynamics simulations of magnetic soft matter are coupled self-consistently with the magnetisation dynamics inside the particles.

Micromagnetic simulations are an important tool for studying microscopic magnetic devices such as sensors and magnetic storage systems. The micromagnetic model describes static and dynamic magnetisation processes using partial differential equations.

Our group develops simulation codes based on finite-element and finite-difference methods. This Master’s project focuses on numerical algorithms that improve the efficiency of these simulations and allow larger systems to be studied.

Possible topics include FFT-accelerated stray-field algorithms, optimisation of finite-element codes for parallel computing, and the development of combined finite-difference/finite-element methods.

Candidates should have an interest in programming and numerical algorithms.

Master’s projects in this area focus on the design and characterisation of diffractive optical elements for cold and very cold neutrons. The work combines optical holography with photosensitive materials such as polymer nanocomposites.

Current topics are located at the interface of materials science, nonlinear optics, and neutron optics. Experiments are carried out in local laboratories as well as at international research centres, for example in France and Switzerland.

This project focuses on magnetic skyrmions, which are tiny vortex-like magnetic structures that may be useful for future data storage technologies.

The Master’s thesis aims to advance micromagnetic simulations for a novel storage concept based on skyrmions and antiskyrmions. These structures could be used to represent binary information states.

The project focuses on developing reliable methods to generate, manipulate, write, and read skyrmions and antiskyrmions. The long-term goal is to improve data storage density, access speed, and energy efficiency.

Supervisor: Dieter Suess

This Master’s project investigates non-reciprocal magnonic phenomena in two- and three-dimensional hybrid nanostructures. Such systems are relevant for the development of microwave devices and sensors.

The project is connected to components such as circulators, isolators, and phase shifters, which are important in communication systems and future quantum technologies. The work involves theoretical modelling and micromagnetic simulations to estimate and optimise the power transmitted by spin waves.
