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…
Spin-reorientation as a switch for electronic topology in van der Waals ferromagnets
Satyabrata Bera, Sudipta Chatterjee, Suman Kalyan Pradhan +5
The interplay between spin reorientation and topological electronic structure in two-dimensional (2D) van der Waals (vdW) ferromagnets is central to understanding how magnetic anis…
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…
