In the quiet architecture of matter, a team at Rice University has found that ruthenium dioxide — long dismissed as non-magnetic — harbors a newly identified form of magnetism when pressed into films only a few atomic layers thick. The discovery, published in Science Advances, reveals that a material's identity is not fixed but shaped by its form and the pressures it endures, much as character is revealed only under certain conditions. This finding, rooted in the emerging science of altermagnetism, suggests that the boundary between magnetic and non-magnetic may be less a wall than a threshold
