MSc thesis project on artificial frustrated spin systems
Artificial spin ice systems consist of dipolar coupled nanomagnets lithographically arranged onto a variety of two- and three-dimensional lattices. Using appropriate imaging techniques, these systems allow the direct visualization of novel and exotic magnetic phases and direct control over their collective behavior at the nanoscale.
Our group is looking for a highly-motivated MSc student to work on one of the following projects:
Project option 1
In collaboration with researchers at Lawrence Berkeley National Lab and Los Alamos National Lab, we aim to explore novel emergent phenomena occurring in three-dimensional artificial spin ice systems. The student’s expected tasks within this project can be summed up as follows:
- Joining experiments at the Advanced Light Source (USA) or Swiss Light Source (Switzerland).
- Analyzing acquired data from these experimental trips. Data interpretation with support from the group and theory collaborators from Los Alamos National Lab.
- Summing up obtained results and participation in manuscript preparation for submissions to scientific journals.
Project option 2
Nanofabrication (at Aalto’s Micronova cleanroom facilities) and investigation of artificial spin ice patterns using ferromagnetic resonance (FMR) techniques. The main goal of the project is to shed light into the role of controlled disorder in influencing acquired FMR measurements. Micromagnetic simulations supporting experimental observations will also be performed within the scope of the project.
