A Simple Method to Transform Soft Magnets into Hard Magnets
A team of researchers at the 伟德国际_伟德国际1946$娱乐app游戏 of Augsburg has discovered a groundbreaking method to turn a soft magnet into a hard one using nothing more than moderate uniaxial stress - pressure applied in a single direction. Their findings were recently published in the prestigious journal Physical Review Letters.

Hall-effect uncovers hidden symmetry in spin-ice
Physicists from the 伟德国际_伟德国际1946$娱乐app游戏 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 伟德国际_伟德国际1946$娱乐app游戏 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.

Basic research: Novel quantum magnets
Over the next two years, Alexander von Humboldt fellow Dr. Prashanta Mukharjee will be carrying out research on novel quantum magnets. What the team of physicists at the Center for Electronic Correlation and Magnetism at the 伟德国际_伟德国际1946$娱乐app游戏 of Augsburg hopes to achieve from the research project with regard to quantum information technology and why the guest researcher from India also has an interest in teaching.

Unexpected emergent low-temperature magnetic correlations
High-resolution capacitive dilatometry down to Millikelvin temperatures in combination of synchrotron, muon and neutron spectroscopy uncovers antiferromagnetic correlations in the strongly valence fluctuating Kondo lattice CeIrSn

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 伟德国际_伟德国际1946$娱乐app游戏 of Augsburg used their recent experience in creating quantum-disordered magnetic states to design a promising new material for adiabatic demagnetization cooling.

伟德国际_伟德国际1946$娱乐app游戏lic compound with magnetic monopoles
Breaking a magnet into two pieces, reveals a north and a south pole in each of them. Independent magnetic monopoles have been known as emergent excitations in one special class of magnetic crystals only. Researchers of the 伟德国际_伟德国际1946$娱乐app游戏 of Augsburg together with international collaboration partners found a new flavor of magnetic monopoles in a material which is even electrically conducting.

伟德国际_伟德国际1946$娱乐app游戏 with unusual properties
A Chinese-German research cooperation involving the 伟德国际_伟德国际1946$娱乐app游戏 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.
