Researchers have unveiled a groundbreaking discovery in the field of material science: ultrathin films of ruthenium dioxide are capable of exhibiting altermagnetism when subjected to lattice strain. This phenomenon presents a distinct form of magnetism that contrasts sharply with the magnetic properties of bulk ruthenium dioxide.
The study, published in Science Advances, delves into the electron spin behavior of the material using spin-resolved angle-resolved photoemission spectroscopy. This advanced technique allowed scientists to analyze the spin texture of ultrathin ruthenium dioxide, revealing unconventional magnetic states previously undetectable in its bulk form.
Key Findings
