About This PhD Project

Project Description

Magnetism and the effects of Electric Field (MagnEFi) an Innovative Training Network funded by the Marie Skłodowska-Curie Actions programme of the European Commission (https://magnefi.c2n.u-psud.fr/) . In this project European experts assembled to provide enhanced training and education to early stage researchers on the topic of electric field effects on nanoscale magnetic structures and to make a scientific impact in terms of the design and performance of multi functional spintronics devices. Research in this area is expected ultimately to lead to ultralow power devices for computation and communication with new functionalities.

The industry partners in this consortium Sensitec (https://www.sensitec.com ) and Singulus AG (https://www.singulus.com/en.html ) have open positions where research on above topics is done in close cooperation with the Johannes Gutenberg University of Mainz, which will be the PhD granting institution.

At Sensitec, a producer of magnetoresistive sensors, the control of strain in magnetoresistive elements and its utilization is in the focus of interest. Magnetoresistive (MR) sensors consist of magnetic thin films and micro- to nanostructures. It is important to understand the behaviour of magnetic domain walls in these structures, to be able to optimize the performance of the sensors. Strain or mechanical stress is, up to now, always seen as a negative impact on MR sensors. In this project, the influence of strain on MR sensor will be studied with two aspects. On the one hand, the conventional approach of minimizing the sensitivity of the sensor to strain by means of design and choice of materials will be pursued. On the other hand, the utilization of strain to realise new or improved functionalities will be a goal.

At Singulus, a manufacturer of industrial thin film deposition tools, the focus is on advanced materials deposition. Electric field effects can be used to induce changes of the magnetic properties and resulting magnetoresistance effects. This can result in novel approaches where information is not encoded in discrete values and processed in Boolean logic gates but novel neuromorphic computing schemes can be employed. In this project, we will develop and deposit high quality material stacks for experiments of electric field manipulation. In particular using high-k dielectrics and ionic conductors can be used to continuously tune the magnetic properties such as anisotropies, the strength of the exchange interactions leading to a control of the spin structures including the Curie temperature, etc.
