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.

Three Humboldt fellows to conduct research in Augsburg

Three researchers from India and China will visit the University of Augsburg for their research fellowship sponsored by the Alexander von Humboldt Foundation (AvH). Each researcher will spend two years researching in different chairs. The researchers include two scientists working in the field of experimental condensed matter physics and a mathematician specialising in computational mathematics.

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.
