NASA’s Curiosity rover, exploring Vera Rubin Ridge in Gale Crater, has identified high concentrations of hematite—an iron-oxide mineral formed in water—raising questions about Mars’ ancient, water-rich environment; the mission also notes unique Martian dunes and continues to study oxidation and past habitability while navigating mechanical wear.
After a century-long search, scientists have discovered emergent magnetic monopole behavior in hematite, an iron-oxide component of rust, which could lead to advancements in data storage and computing technologies. Using a technique called "diamond quantum magnetometry," researchers from the U.K. and China were able to capture the first naturally occurring magnetic monopoles emerging from collective electron behavior in flecks of hematite. While this discovery doesn't definitively prove the existence of separated magnetic poles, it opens the door to potential developments in next-generation storage techniques and ultra-efficient computing devices.
Physicists have discovered seemingly impossible one-sided magnets, known as monopoles, on the surface of hematite, a mineral made of iron oxide. By using an imaging technique called diamond quantum magnetometry, researchers found that groups of particles on the hematite's surface combine their properties to create the effect of a single particle with just one magnetic pole. This discovery could potentially lead to more energy-efficient computer memory by allowing engineers to have greater control over magnetic spin.
Researchers have measured quasiparticles with single, double, and quadruple magnetic poles on the surface of hematite, a rock similar to rust. These peculiar magnetic configurations, known as magnetic monopoles, were observed for the first time in a naturally occurring magnet. The formation of these monopoles is connected to the property of emergence, where the combination of many physical entities produces something new with unique properties. The discovery could have implications for improving computer technology and memory logic.
Researchers at the University of Cambridge have discovered magnetic monopoles in hematite, a material similar to rust, using diamond quantum sensing. This breakthrough observation of emergent monopoles, which behave like isolated magnetic charges, could revolutionize computing technology by enabling faster and more environmentally friendly applications. The researchers observed that these magnetic monopoles in hematite emerge through the collective behavior of many spins, gliding across swirling textures on the material's surface. This is the first time that naturally occurring emergent monopoles have been experimentally observed, and it could unlock new avenues in quantum material research.
Researchers have used diamond quantum sensing to observe magnetic monopoles, isolated magnetic charges, in hematite, a type of iron oxide. These monopoles glide across swirling textures on the surface of hematite, and their emergence through collective behavior of many spins has been observed experimentally for the first time. The study reveals a direct connection between the swirling textures and magnetic charges, potentially enabling next-generation logic and memory applications in computing technologies.
Scientists at the National Synchrotron Light Source II (NSLS-II) have discovered a previously unknown spectrum of magnon excitations in an antiferromagnetic thin film made of hematite. Magnon excitations are of interest for spintronics applications, as they allow for information transfer without the need for electron movement. The research team used the Soft Inelastic X-ray Scattering (SIX) beamline at NSLS-II to measure the behavior of magnon waves in the thin film, revealing both familiar and previously unseen modes of excitation. The findings contribute to a better understanding of the fundamental behavior of materials used in spintronics and may aid in the design of more efficient devices.
