Humboldt-Stiftung fördert Spin-Eis-Forschung

Die wissenschaftliche Mitarbeiterin Dr. Nan Tang vom Lehrstuhl für Experimentalphysik VI wird seit Kurzem von der Humboldt-Stiftung gefördert. Sie beschäftigt sich mit Spin-Materialien und quantenkritischen Phänomenen stark korrelierender Materialien. Bei Tangs wichtigstem Projekt geht es um das sogenannte Spin-Eis, ein Material, das unter niedrigen Temperaturen besondere magnetische Bindungen eingeht.

Hall-effect uncovers hidden symmetry in spin-ice

Physicists from the University of Augsburg succeeded to distinguish chiral orders with similar magnetization but opposite sense of rotation through electrical measurements at low temperatures. This is relevant for fundamental research on complex magnets and with respect to possible applications for magnetic data storage. The results were published in the renowned journal Nature Physics.

Quantum boost for a classical cooling technology: new material

Cooling is a long-standing technological challenge. Standard cooling cycle based on vapor compression exploits expensive helium gas to reach temperatures near absolute zero. Adiabatic demagnetization known since nearly a century could be a viable alternative if compact and durable paramagnetic materials were available. A team of researchers from the University of Augsburg used their recent experience in creating quantum-disordered magnetic states to design a promising new material for adiabatic demagnetization cooling.

Metallic compound with magnetic monopoles

Breaking a magnet into two pieces, reveals a north and a south pole in each of them. Independent magnetic monopoles have been known as emergent excitations in one special class of magnetic crystals only. Researchers of the University of Augsburg together with international collaboration partners found a new flavor of magnetic monopoles in a material which is even electrically conducting.

Metal with unusual properties

A Chinese-German research cooperation involving the University of Augsburg has demonstrated properties in a metal that cannot be explained by the standard theory. The results were obtained on a special metallic compound with unusual magnetic characteristics – scientists call it magnetic frustration.  The cooperation observed a novel, “quantum critical behaviour” in the metal at very low temperatures and at high pressures and strong magnetic fields.
