Sub-wavelength mid-infrared imaging of locally driven photocurrents using diamond campanile probes
Rajasekhar Medapalli, Nathan D. Cottam, Khushboo Agarwal +12
Precise and high efficiency concentration of mid-infrared (mid-IR) light into sub wavelength volumes is essential for probing low-energy excitations and achieving strong field enha…
Spin and lattice dynamics at the spin-reorientation transitions in the rare-earth orthoferrite SmTbFeO
R. M. Dubrovin, A. I. Brulev, N. R. Vovk +10
Linear and non-linear couplings of magnetic and lattice excitations are at the heart of many fascinating magnetophononic phenomena observed in rare-earth orthoferrites, the distinc…
Photoengineering the Magnon Spectrum in an Insulating Antiferromagnet
V. Radovskaia, R. Andrei, J. R. Hortensius +9
Femtosecond optical pulses have opened a new frontier in ultrafast dynamics, enabling direct access to fundamental interactions in quantum materials. In antiferromagnets (AFMs), wh…
Laser-induced helicity and texture-dependent switching of nanoscale stochastic domains in a ferromagnetic film
Dinar Khusyainov, Rein Liefferink, MengXing Na +10
Controlling magnetic textures at ever smaller length and time scales is of key fundamental and technological interest. Achieving nanoscale control often relies on finding an extern…
Lattice dynamics and mixing of polar phonons in the rare-earth orthoferrite TbFeO
R. M. Dubrovin, E. M. Roginskii, V. A. Chernyshev +10
Rare-earth orthoferrites are a promising platform for antiferromagnetic spintronics with a rich variety of terahertz spin and lattice dynamics phenomena. For instance, it has been…
