Altermagnetism and Anomalous Transport in Ag Fluorides: KAgF and KAgF
First-principles calculations reveal that Ag-based fluorides KAgF and KAgF exhibit distinct magnetic and orbital orderings, where the A-type antiferromagnetic KAgF displays altermagnetic properties with significant anomalous transport and magneto-optical responses, while the conventional antiferromagnetic KAgF preserves symmetry and lacks such anomalous effects.
