Strain-induced atomic-scale building blocks for ferromagnetism in epitaxial LaCoO3
Sangmoon Yoon, Xiang Gao, Jong Mok Ok +7
The origin of strain-induced ferromagnetism, which is robust regardless of the type and degree of strain in LaCoO3 (LCO) thin films, is enigmatic despite intensive research efforts…
Twin-domain formation in epitaxial triangular lattice delafossites
Jong Mok Ok, Sangmoon Yoon, Andrew R. Lupini +4
Twin domains are often found as structural defects in symmetry mismatched epitaxial thin films. The delafossite ABO2, which has a rhombohedral structure, is a good example that oft…
Effective reduction of PdCoO2 thin films via hydrogenation and sign tunable anomalous Hall effect
Gaurab Rimal, Yiting Liu, Caleb Schmidt +14
PdCoO2 , belonging to a family of triangular oxides called delafossite, is one of the most conducting oxides. Its in-plane conductivity is comparable to those of the best metals, a…
Unusual Electrical Conductivity Driven by Localized Stoichiometry Modification at Vertical Epitaxial Interfaces
Wenrui Zhang, Shaobo Cheng, Christopher M Rouleau +7
Precise control of lattice mismatch accommodation and cation interdiffusion across the interface is critical to modulate correlated functionalities in epitaxial heterostructures, p…
Investigating phase transitions from local crystallographic analysis based on machine learning of atomic environments
Rama K. Vasudevan, Maxim Ziatdinov, Lukas Vlcek +8
Traditionally, phase transitions are explored using a combination of macroscopic functional characterization and scattering techniques, providing insight into average properties an…
Unraveling ferroelectric polarization and ionic contributions to electroresistance in epitaxial Hf0.5Zr0.5O2 tunnel junctions
Milena Cervo Sulzbach, Saúl Estandía, Xiao Long +7
Tunnel devices based on ferroelectric Hf0.5Zr0.5O2 (HZO) barriers hold great promises for emerging data storage and computing technologies. The resistance state of the device can b…
