New Superconductors in the PtPbBi Structure Type
Lior Verbitsky, Amira Merino, Scott B. Lee +8
The quest for new superconductors is of both fundamental and technological importance. Recently, an artificial intelligence method correctly predicted PtPbBi to be a supercondu…
Tunable magnetotransport through kinetically hindered first-order phase transitions in an antiferromagnetic metal
Jaime M. Moya, Scott B. Lee, Sudipta Chatterjee +4
Controllable multilevel resistance states are of interest for memory technologies like neuromorphic computing, but robust materials platforms toward such behavior remain limited. H…
Stripping Symmetry: Electrochemical Oxidation to a Superconducting Polar Metal in Au2Pb0.914P2
Scott B. Lee, Stephanie R. Dulovic, Joseph W. Stiles +11
Polar metals and noncentrosymmetric superconductors are exceptionally rare, yet their broken inversion symmetry can give rise to emergent electronic phenomena including mixed singl…
Collinear spin density wave state in distorted square-lattice GdNiSn
Charles C. Tam, Sarah Schwarz, Xin Zhang +5
We characterize the magnetic ground state of the newly synthesized lanthanide intermetallic GdNiSn via resonant elastic x-ray scattering measurements. This compound forms disto…
New Crystal Structures Hide in Plain Sight: A Stress Test for AI-Guided Materials Discovery
Xin Zhang, Scott B. Lee, Sudipta Chatterjee +14
New types of crystal structures are discovered only rarely, and the artificial intelligence (AI) models now reshaping materials discovery have so far produced new chemical composit…
Measuring the Hall effect in hysteretic materials
Jaime M. Moya, Anthony Voyemant, Sudipta Chatterjee +4
Measurement of the Hall effect is a ubiquitous probe for materials discovery, characterization, and metrology. Inherent to the Hall measurement geometry, the measured signal is oft…
Electron-affinity difference distributions as an organizing principle for superconductivity, enabling the discovery of PtPbBi
Omri Lesser, Yanjun Liu, Natalie Maus +11
Predicting the superconducting transition temperature () from crystal structure and composition remains a central challenge in condensed-matter physics, reflecting the absence…
Directionally Locked Heteroepitaxy with a Structurally Modulated van der Waals Material
Nitish Mathur, Guangming Cheng, Francesc Ballester +17
Precise orientation of symmetry-mismatched epilayers on van der Waals (vdW) substrates via heteroepitaxy has commonly been achieved through surface treatment processes to accommoda…
Bonding Interactions Can Drive Topological Phase Transitions in a Zintl Antiferromagnetic Insulator
Tanya Berry, Jaime M. Moya, David Smiadak +5
While 30% of materials are reported to be topological, topological insulators are rare. Magnetic topological insulators (MTI) are even harder to find. Identifying crystallogr…
