New Form of Magnetism Discovered in Lab-Made Crystal

Researchers have made a groundbreaking discovery in the field of magnetism, uncovering a new type of magnetism within a crystal created in the laboratory. This finding not only holds promise for enhancing efficiency and speed in electronics but also opens up new avenues for exploration in fundamental physics.

A team of international scientists, building upon previous theoretical predictions, identified p-wave magnetism in nickel iodide (NiI2), a two-dimensional crystal that possesses the specific properties required for this unique form of magnetism to manifest.

MIT physicist Riccardo Comin explains, “It was a completely new idea at the time, and we decided to test it experimentally because we realized nickel iodide was a good candidate to show this kind of p-wave magnet effect.”

In traditional magnets, electrons align their spins in the same direction, creating a magnetic field. Antiferromagnets, on the other hand, have spins that cancel out at the macro scale.

P-wave magnetism blends ferromagnetism with antiferromagnetism in a way that generates mirrored spirals of various spin states, effectively nullifying the magnetism on a larger scale. Thin flakes of nickel iodide produced in a high-temperature furnace allowed electrons to spin in different directions based on their immediate surroundings.

Utilizing polarized light, which oscillates like a corkscrew, researchers were able to reveal spiral-like configurations among the spins of electrons in the material. Furthermore, they demonstrated the ability to control this novel form of magnetism, adjusting its spin state and properties using a small electric field.

Physicist Qian Song from MIT notes, “This breakthrough paves the way for a new class of ultrafast, compact, energy-efficient, and nonvolatile magnetic memory devices.”

This discovery could revolutionize the field of spintronics, enabling the manipulation of electron spins for memory storage, computation, and energy transfer. By switching electron spins in a controlled manner, this technology has the potential to lead to denser, faster, and more energy-efficient memory chips.

While practical applications are still in the development phase, the long-term implications of p-wave magnets could result in electronics that operate on manipulated electron spins rather than electric charges, vastly improving efficiency.

According to Song, “P-wave magnets could save five orders of magnitude of energy. Which is huge.”

The research findings have been published in Nature.
