Every time a computer processes information, electrons shuttle through circuits carrying electric charge, and much of the energy they carry is wasted as heat. Spintronics proposes a different approach: instead of relying solely on the charge of electrons, exploit another of their properties called spin, a quantum-mechanical quantity that can be thought of as a […]

Imagine electrons as tiny particles zipping through a material, each carrying two key properties: charge, which powers our everyday electronics, and spin, like a little internal compass needle that points up or down. Charge flow is what we call electric current, but spin adds a magnetic twist, opening doors to advanced technologies like more efficient […]

When Georg Ohm wired up pieces of copper in 1827, he struck a rule so robust that it still underpins every phone and supercomputer on Earth: double the current, double the voltage. Simple, linear, universal—or so we thought. Over the past decade physicists have discovered that this bedrock principle crumbles the moment a crystal loses […]

Nanotechnology is like a playground for scientists, where they tinker with materials at the scale of atoms to create new tools and devices with extraordinary properties. One of the most exciting areas in this field involves nanographenes, which are tiny pieces of graphene—a single layer of carbon atoms arranged in a honeycomb pattern, known for […]

Spintronics is a field of technology that focuses on using the spin of electrons—an intrinsic property that can be thought of as a tiny magnetic moment—to store and process information. This concept is based on the fact that electrons, in addition to carrying electric charge, also have a “spin,” which can be oriented in different […]

Molecular spintronics is an emerging field that combines ferromagnetic materials with organic or metal–organic semiconductors. It benefits from the unique and exceptional properties of organic molecules, which go beyond inorganic ones. The strong response of many organic molecules to electrical, optical, ferromagnetic or antiferromagnetic stimuli bring new potential functionalities to the spintronic device. An effective […]

Hopfions, magnetic spin structures predicted decades ago, have become a hot and challenging research topic in recent years. The first experimental evidence has just been presented in Nature . A deeper understanding of how different components of materials function is important for the development of innovative materials and future technology. The research field of spintronics […]

pair-density-wave Scientists have revealed a new phase of matter in candidate topological superconductors that could have significant consequences for condensed matter physics and for the field of quantum computing and spintronics. Researchers at the Macroscopic Quantum Matter Group at Cornell University have discovered and visualized a crystalline yet superconducting state in a new and unusual […]

One-dimensional metal−organic chains often possess a complex magnetic structure, susceptible to modification by alteration of their chemical composition. The possibility to tune their magnetic properties provides an interesting playground to explore quasi-particle interactions in low-dimensional systems. These systems have potential applications in the fabrication of nanodevices for spin sensing, spintronics, quantum computing based on the […]

Spintronic devices are based on the inherent spin magnetic moment of the electron, the same way electronic ones are on just its charge, to store and process information. These devices should, in theory, operate faster and at lower temperatures than their current electronic-only counterparts because an electron’s spin can be flipped much quicker than its […]
