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-…
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…
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…
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…
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…
