Altermagnetism arises from a combination of crystal symmetry and magnetic ordering. For the altermagnetic properties to be clear, and technologically useful, the same crystal variant must be present over the entire sample. Here, He, Wen and coauthors achieve such single variant thin films in RuO2, confirming the altermagnetic properties via XMLD and transport measurements.
