Anisotropic Superconductivity with Enhanced Critical Field in Strained RuO2
Younes Ghorbani, Samuel Poage, Xuehsi Gao +9
The superconductivity in RuO2 emerges under strain. RuO2 is also an altermagnet candidate. The nature of superconductivity and its relation with neighboring orders, however, are no…
Crystallography of periodic nanotextures in a strained Mott insulator
Benjamin Z. Gregory, Yorick A. Birkhölzer, Noah Schnitzer +9
Here we investigate stripes of alternating structural phases spontaneously forming in epitaxially strained thin films below the metal-insulator transition. Using large-…
Martensitic laminate geometry controls electronic phase transitions in a Mott insulator
Ziming Shao, Benjamin Gregory, Suchismita Sarker +4
Symmetry-lowering structural phase transitions result in multiple degenerate structures whose coexistence is determined by macroscopic strain compatibility. In quantum materials, t…
Synthesis of epitaxial TaO thin films on AlO by suboxide molecular-beam epitaxy and thermal laser epitaxy
Yorick A. Birkhölzer, Anna S. Park, Noah Schnitzer +28
Tantalum dioxide (TaO2) is a metastable tantalum compound. Here, we report the epitaxial stabilization of TaO2 on Al2O3 (1-102) (r-plane sapphire) substrates using suboxide molecul…
Resonant diffraction and photoemission inconsistent with altermagnetism in epitaxial RuO films
Benjamin Z. Gregory, Neha Wadehra, Shuyuan Zhang +15
Excitement about the magnetic and electronic properties of RuO is growing, fueled by reports of antiferromagnetism, strain-induced superconductivity, and its recent classificat…
DONUT: Physics-aware Machine Learning for Real-time X-ray Nanodiffraction Analysis
Aileen Luo, Tao Zhou, Ming Du +3
Coherent X-ray scattering techniques are critical for investigating the fundamental structural properties of materials at the nanoscale. While advancements have made these experime…
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…
Anisotropic Spin Stripe Domains in Bilayer LaNiO
N. K Gupta, R. Gong, Y. Wu +10
The discovery of superconductivity in LaNiO under pressure has motivated the investigation of a parent spin density wave (SDW) state, which could provide the underlying…
Deep Learning of Structural Morphology Imaged by Scanning X-ray Diffraction Microscopy
Aileen Luo, Tao Zhou, Martin V. Holt +2
Scanning X-ray nanodiffraction microscopy is a powerful technique for spatially resolving nanoscale structural morphologies by diffraction contrast. One of the critical challenges…
X-ray Nano-imaging of a Heterogeneous Structural Phase Transition in V2O3
Ziming Shao, Aileen Luo, Eti Barazani +5
Controlling the Mott transition through strain engineering is crucial for advancing the development and application of memristive and neuromorphic computing devices. Yet, Mott insu…
Spontaneous supercrystal formation during a strain-engineered metal-insulator transition
O. Yu. Gorobtsov, L. Miao, Z. Shao +13
Mott metal-insulator transitions possess electronic, magnetic, and structural degrees of freedom promising next generation energy-efficient electronics. We report a previously unkn…
Strain-induced orbital energy shift in antiferromagnetic RuO2 revealed by resonant elastic x-ray scattering
Benjamin Gregory, Jörg Strempfer, Daniel Weinstock +7
In its ground state, RuO2 was long thought to be an ordinary metallic paramagnet. Recent neutron and x-ray diffraction revealed that bulk RuO2 is an antiferromagnet (AFM) with TN a…
