Title: A NEW KIND OF MAGNET.
Authors: HENDERSON, BOB (AUTHOR)
Source: Scientific American. May2026, Vol. 334 Issue 5, p32-43. 12p. 5 Color Photographs, 1 Diagram.
Subjects: Magnetic materials, Magnetic properties, Antiferromagnetic materials, Spin-polarized currents, Magnetic memory (Computers), Ferromagnetic materials, Spintronics
Abstract: The article focuses on the discovery and implications of altermagnets, a newly identified class of magnetic materials that combine features of ferromagnets and antiferromagnets through unique symmetry properties. Unlike traditional ferromagnets, which have aligned electron spins producing a net magnetic field, and antiferromagnets, which have opposing spins that cancel out magnetization, altermagnets break time-reversal symmetry while retaining a combined symmetry involving a 90-degree atomic rotation, enabling novel magnetic effects such as spin-polarized currents without net magnetization. This breakthrough challenges conventional understanding of magnetism and holds promise for advancing spintronics and memory technologies, including potentially faster and more energy-efficient devices, although practical applications face significant material and engineering challenges. The research highlights the importance of symmetry in magnetic behavior and opens new avenues for exploring magnetic materials beyond established categories. [Extracted from the article]
