Tailoring topological altermagnetic spin texture via interfacial exchange coupling in quasi-2D CrSb/(Bi, Sb)2Te3 thin film
. The effective Hamiltonian model reveals that the exchange coupling between the altermagnetic order and topology can produce a unique hybrid anomalous Hall effect. Angle-dependent magneto-transport investigation uncovers the magnetic dynamics of altermagnetic moments with exchange coupling. Our strategy broadens the way to explore altermagnetic interfacial physics and topological spintronics in quasi-2D altermagnet/topological insulator heterostructures.
