    "body_text": "Researchers grew fully strained, two-nanometer ruthenium-dioxide films and used spin- and angle-resolved photoemission to examine a disputed material. The observed spin texture survived symmetry and artifact checks and was compatible with weak ferromagnetism or altermagnetism. The measurements were made near 15 kelvin, so room-temperature behavior remains unknown; the study establishes strain as a plausible control knob, not a finished spintronic device.",
