45. We note that potential multiple reflections in these heterostructures will only affect the magnitude of the time-integrated static reflectivity, without influencing the time-resolved signal, particularly since only the properties of LCMO are directly changing with time after photoexcitation.

47. In G-type BFO, spins are aligned perpendicular to the FE polarization (111) and the equivalent variants. The spin alignment can be projected into in-plane and out-of-plane components. The induced AFM order in LCMO, however, depends mainly on the out-of-plane spin components of BFO since only the perpendicular magnetic susceptibility (Χ⊥) dominates the AFM order, i.e., only a perpendicular field can cant the Néel axis.
