When a topological insulator (TI) is in contact with a ferromagnet, both timereversal and inversion symmetries are broken at the interface. An energy gap isformed at the TI surface, and its electrons gain a net magnetic moment throughshort-range exchange interactions. Magnetic TIs can host various exotic quantumphenomena, such as massive Dirac fermions, Majorana fermions, the quantumanomalous Hall effect and chiral edge currents along the domain boundaries.However, selective measurement of induced magnetism at the buried interface hasremained a challenge. Using magnetic second harmonic generation, we directlyprobe both the in-plane and out-of-plane magnetizations induced at theinterface between the ferromagnetic insulator (FMI) EuS and thethree-dimensional TI Bi2Se3. Our findings not only allow characterizingmagnetism at the TI-FMI interface but also lay the groundwork for imagingmagnetic domains and domain boundaries at the magnetic TI surfaces.
