Scientists spin diamonds at a billion RPM to test the limits of physics








Representative image of diamond-shaped crystals adorning a wall. Purdue University physicists have reported levitating nanodiamonds in a vacuum and spinning them very fast. It sounds like a simple, even comical, feat but is actually quite difficult.

As scientists’ understanding of the basic properties of matter has improved over time, they have been able to engineer materials with the best properties for specific applications. Such bespoke materials have revolutionised various sectors, including medical diagnostics, spaceflight, cryptography, commercial electronics, and computing. One such material is the fluorescent nanodiamond (FND).

FNDs are nanometre-sized diamonds made of carbon nanoparticles. They are produced in a high temperature and high pressure process. FNDs are stable under light and aren’t toxic to living things, so they have many applications in high-resolution imaging, microscale temperature sensing, and correlative microscopy, among others. In biology, scientists use FNDs to track cells and their progeny over long periods.

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...

Scientists Discover New “Hall Effect” That Could Revolutionize Electronics

Scientists discovered a new Hall effect driven by spin currents in noncollinear antiferromagnets, offering a path to more efficient and resilient spintronic devices . A research team led by Colorado State University graduate student Luke Wernert and Associate Professor Hua Chen has identified a previously unknown type of Hall effect that could lead to more energy-efficient electronic devices . Their study, published in Physical Review Letters, was conducted in collaboration with graduate student Bastián Pradenas and Professor Oleg Tchernyshyov of Johns Hopkins University. The researchers uncovered evidence of a new property, dubbed the “Hall mass,” in a class of complex magnetic materials known as noncollinear antiferromagnets . The traditional Hall effect, discovered by Edwin Hall at Johns Hopkins in 1879, describes how an electric current is deflected sideways when subjected to an external magnetic field, generating a measurable voltage. This effect plays a crucial role in technologi...
