Comparison of MnO and NiO terahertz excitation dynamics

Determine how the excitation dynamics of MnO compare with the well-established terahertz-driven excitation dynamics of NiO.

Background

Manganese oxide (MnO) and nickel oxide (NiO) are structurally related antiferromagnetic insulators with terahertz-frequency antiferromagnetic resonances. Although coherent terahertz-driven spin dynamics have been extensively studied in NiO, direct time-domain measurements of the response of MnO to strong terahertz excitation remain limited. The paper identifies the comparison between the excitation dynamics in the two materials as unresolved, motivating the reported phase-resolved measurements of MnO.

References

However, direct time-domain measurements of the coherent MnO response to strong THz excitation remain limited, leaving open how the excitation dynamics compare with the well-established behavior in NiO.
