Ultrasensitive strain modulation of terahertz magnons at a magnetic phase transition
Lichen Wang, Sajna Hameed, Yiran Liu +8
Antiferromagnets typically host spin-wave (magnon) excitations in the terahertz (THz) regime, offering a promising platform for high-speed magnonic information technologies. Harnes…
Uniaxial strain tuning of polar lattice vibrations in KTaO and SrTiO
I. Khayr, N. Somun, S. Hameed +11
The interplay of electronic and structural degrees of freedom is a prominent feature of many quantum materials and of particular interest in systems with strong ferroelectric fluct…
Non-collinear and strongly asymmetric polar moments at back-gated SrTiO3 interfaces
Fryderyk Lyzwa, Yurii G. Pashkevich, Premysl Marsik +15
The highly mobile electrons at the interface of SrTiO3 with other oxide insulators, such as LaAlO3 or AlOx, are of great current interest. A vertical gate voltage allows controllin…
Control of the metal-insulator transition in NdNiO thin films through the interplay between structural and electronic properties
Y. E. Suyolcu, K. Fürsich, M. Hepting +10
Heteroepitaxy offers a new type of control mechanism for the crystal structure, the electronic correlations, and thus the functional properties of transition-metal oxides. Here, we…
