Temperature-dependent optical SHG measurements of BFO films grown on different substrates. a SHG results in a wide temperature range of BFO films grown on LSAT, STO, DSO, GSO, and KTO substrates, respectively. b–f Temperature-dependent SHG signals contributed from antiferromagnetic order of BFO films grown on LSAT, STO, DSO, GSO, and KTO substrates, respectively. The orange solid lines are fitted results. g \({T}_{{\rm{N}}}\) as a function of misfit strain for BFO films grown on different substrates. h SHG intensity contributed from the antiferromagnetic order of BFO films grown on different substrates as a function of misfit strain
