A team of scientists from the MPI CPFS and Stockholm, Tsukuba, Oxford, Toronto, St Andrews and Birmingham combined focused ion beam microstructuring and uniaxial pressure to achieve a record value of uniaxial pressure for the unconventional superconductor Sr2RuO4 and found that the superconducting state of Sr2RuO4 evolved surprisingly.
Working with a new experimental technique called the ac elastocaloric effect, a team of scientists from Dresden, Karlsruhe, St Andrews, Cornell, Tsukuba and Stanford has mapped out the so-called phase diagram of the unconventional superconductor Sr2RuO4. The results narrow down the on-going, 25 years quest to understand the superconductivity of Sr2RuO4 and set a benchmark for future work.
Observations reveal the angle dependence of the magnetic field needed to suppress superconductivity in CeRh2As2. Uniquely, the behavior of “odd parity” superconductors is revealed.
An international research team has discovered that topological electronic states are present in nearly every known material for every electron in the crystal configuration. Appearing this week in Science, the team’s discovery of ubiquitous band topology has motivated re-examining previous experimental data for overlooked topological features, and…
The study of ultra-pure materials still has many ways to surprise and delight! For delafossite metals it was shown that wires sculpted from the same single crystal have very different resistivities depending on the angle at which they are cut. From the fundamental physics point of view, the laws of bulk resistivity are being broken.
We are happy to announce that Professor Joshua Goldberger from The Ohio State University in the United States has been awarded a Friedrich Wilhelm Bessel fellowship sponsored by the Humboldt foundation. This prestigious fellowship entitles him to spend a sabbatical in Germany, most of the time at our institute in the department of Solid State…
Two bistable and reversibly controllable antiferromagnetic states in strained BiFeO3 (BFO) films are discovered. These two non-volatile antiferromagnetic states are successfully patterned with a non-contact approach combining both optical and magnetic methods. The written antiferromagnetic pattern is electrically readable with at least 30% signal difference. This work promises an efficient route toward practical applications of antiferromagnetic spintronics.
Spintronic devices are based on using the fundamental spin of electrons to carry and store information. Their use would not require charge currents for their operation and would lead to improved energy efficiency with lower power consumption, higher data processing speed and better integration of memory and logic. However, suitable materials for…
