Emmy Noether junior research group investigates new magnetic structures for spintronics applications

11.10.2016

New Emmy Noether independent junior research group TWIST to be set up at Mainz University / Skyrmions could one day make the storage media in our computers smaller and more efficient

Theoretical physicist Dr. Karin Everschor-Sitte will be setting up an Emmy Noether independent junior research group at Johannes Gutenberg University Mainz (JGU) with the aid of funding from the German Research Foundation (DFG). The workgroup TWIST – short for Topological Whirls in SpinTronics – will be looking at skyrmions.

These are new magnetic 'particles' named after the physicist Tony Skyrme that could in future ensure that the storage media in our computers become smaller and more efficient. A skyrmion can be described as a kind of node or vortex within a magnetic texture.

Skyrmions are characterized by the fact that they are more stable than any other magnetic structures and react particularly readily to spin currents. This is why skyrmions are considered to be of relevance to technological applications in the field of spintronics, a young physics discipline that is exploring not only the electronic charges of such particles, but also their spin, i.e., their magnetic properties.

The objective of Dr. Karin Everschor-Sitte is to gain a deeper understanding of the interaction between skyrmions, magnetic structures, and spin and charge currents and to develop new theories that will enable her to make the best use of skyrmions in technological applications.

Her future projects could produce some innovative concepts that would be of commercial interest. "We are delighted that Dr. Karin Everschor-Sitte will be contributing to our work in the field of spintronics," says Professor Jairo Sinova, Director of SPICE, the Spin Phenomena Interdisciplinary Center at Mainz University that, alongside the Emmy Noether group to be established in November 2016, is also affiliated with the Condensed Matter Physics (KOMET) work group of the JGU Institute of Physics.

Through its Emmy Noether Program, the German Research Foundation supports young researchers in achieving independence at an early stage of their scientific careers by giving them the opportunity to head a junior research group and thus gain the qualifications required for a university teaching career. Independent junior research groups are usually funded for a period of five years. Dr. Karin Everschor-Sitte worked at the University of Texas at Austin in the USA from 2013 to 2015 and relocated to Mainz in November 2015. She will begin setting up her workgroup at JGU in November 2016.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
