- Layered room-temperature altermagnet shows promise for advanced spintronics 08/05/2025 Traditionally, magnetic materials have been divided into two main categories: ferromagnets and antiferromagnets. Over the past few years, however, physicists have uncovered the existence of altermagnets, a new type of magnetic material that exhibits features of both antiferromagnets and ferromagnets.
- New mechanism uses photonic crystal for concentrating light on a chip 06/05/2025 Concentrating light in a volume as small as the wavelength itself is a challenge that is crucial for numerous applications. Researchers from AMOLF, TU Delft, and Cornell University in the U.S. have demonstrated a new way to focus light on an extremely small scale. Their method utilizes special properties of a photonic crystal and works for a broader spectrum of wavelengths than alternative methods. The researchers published their findings in Science Advances on April 18.

- Scientists unveil new way to electrically control spin for ultra-compact devices using altermagnetic quantum materials 10/04/2025 Spintronics, an emerging field of technology, exploits the spin of electrons rather than their charge to process and store information. Spintronics could lead to faster, more power-efficient computers and memory devices. However, most spintronic systems require magnetic fields to control spin, which is challenging in ultracompact device integration due to unwanted interference between components. This new research provides a way to overcome this limitation.
- New superconducting state discovered: Cooper-pair density modulation 08/04/2025 Superconductivity is a quantum physical state in which a metal is able to conduct electricity perfectly without any resistance. In its most familiar application, it enables powerful magnets in MRI machines to create the magnetic fields that allow doctors to see inside our bodies. Thus far, materials can only achieve superconductivity at extremely low temperatures, near absolute zero (a few tens of Kelvin or colder).
- Organic electrochemical transistors enhance bioelectronic sensor sensitivity by three orders of magnitude 27/03/2025 In a breakthrough that could transform bioelectronic sensing, an interdisciplinary team of researchers at Rice University has developed a new method to dramatically enhance the sensitivity of enzymatic and microbial fuel cells using organic electrochemical transistors (OECTs). The research was recently published in the journal Device.
- A completely new type of microscopy based on quantum sensors 25/03/2025 Researchers at the Technical University of Munich (TUM) have invented an entirely new field of microscopy called nuclear spin microscopy. The team can visualize magnetic signals of nuclear magnetic resonance with a microscope. Quantum sensors convert the signals into light, enabling extremely high-resolution optical imaging.
