Working Group Magnetism

Research

Ferromagnetism is known since the discovery of magnetite in the province magnesia in Asian Minor. Since that time this phenomenon fascinated many people. Today the investigation of magnetism is a growing section of material sciences which has an exceptional impact on information technology, electrical engineering, and automotive applications.

Achieving further progress in this fields requires the investigation and understanding of the characteristic properties of new materials and hybrid systems. The main focus of our research is on the investigation of the electronic origin of macroscopic magnetic particles. A second focus is on interface and surface effects, which dominate magnetic properties for nanoscale system.

Alongside miniaturization in the semiconductor industry, information technology has tremendously benefitted from the exponential increase of magnetic storage density on hard disk drives, doubling the amount of storable information every two years (Moore's Law). New physical effects discovered in the course of storage research pave the way for a new type of electronics called spintronics with the spin instead of the charge being the carrier for information transport.

We study electronic transport and correlation effects for nanoscale and molecular systems using spin-resolving experimental methodes, e.g. spin-polarized scanning tunneling microscopy, spin-resolved photoemission microscopy and x-ray magnetic circular dichroism.
