Strain-Induced Relaxor Multiferroicity at Room Temperature in Hexaferrite BaFe12O19 Thin Films
Yilin Evan Li, Harikrishnan KP, Sankalpa Hazra +19
Multiferroic materials that combine magnetic and electric order at room temperature are rare. Here, we demonstrate strain-induced room-temperature polar order in the ferrimagnetic…
Dynamical Nonrelativistic Spin Splitting via THz Nonlinear Phononics
Linding Yuan, ChanJu You, Ankit Disa +1
Nonrelativistic spin splitting (NRSS) in collinear antiferromagnets, including altermagnets and compensated ferrimagnets, offers a route to high-frequency spintronics immune to str…
Dynamically suppressed lattice rotations in SrTiO as a basis for photo-induced ferroelectricity
Huaiyu Hugo Wang, Michael Fechner, Giovanni De Vecchi +22
Photo-induced ferroelectricity in the quantum paraelectric SrTiO involves the dynamical interplay between a coherently driven Ti-O stretching vibration and multiple structural…
Picosecond expansion in LaAlO3 resonantly driven by infrared-active phonons
Jakob Gollwitzer, Jeffrey Z. Kaaret, Y. Eren Suyolcu +19
We investigate the ultrafast structural dynamics of LaAlO3 thin films driven by short mid-infrared laser pulses at 20 THz. Time-resolved X-ray diffraction reveals an immediate latt…
Sparse Optimization of Two-Dimensional Terahertz Spectroscopy
Zhengjun Wang, Hongju Da, Ankit S. Disa +3
Two-dimensional terahertz spectroscopy (2DTS) is a low-frequency analogue of two-dimensional optical spectroscopy that is rapidly maturing as a probe of a wide variety of condensed…
Excitation-Dependent Features and Artifacts in 2-D Terahertz Spectroscopy
Albert Liu, Ankit Disa
Recently, two-dimensional terahertz spectroscopy (2DTS) has attracted increasing attention for studying complex solids. A number of recent studies have applied 2DTS either with lon…
