Conductivity scaling of the anomalous Hall effect in the altermagnetic semiconductor α-MnTe
Sara Bey, Shelby S. Fields, Nicholas G. Combs +22
α-MnTe is a prototypical altermagnet exhibiting a strong anomalous Hall effect (AHE), despite having a nearly vanishing magnetization. Lately, sample-to-sample variations of the am…
Unexpected Tuning of the Anomalous Hall Effect in Altermagnetic MnTe Thin Films
Sara Bey, Shelby S. Fields, Nicholas G. Combs +10
The discovery of an anomalous Hall effect (AHE) sensitive to the magnetic state of antiferromagnets can trigger a new era of spintronics, if materials that host a tunable and stron…
Spectral analysis of the magneto-optical response in valley polarized PbSnSe
Xiaoqi Ding, Jiashu Wang, Mykhaylo Ozerov +7
Since the last century, considerable efforts have been devoted to the study of valley-degenerate narrow gap semiconductors, such as the PbSnSe alloy. This material poss…
Probing Berry curvature in magnetic topological insulators through resonant infrared magnetic circular dichroism
Seul-Ki Bac, Florian le Mardelé, Jiashu Wang +16
Probing the quantum geometry and topology in condensed matter systems has relied heavily on static electronic transport experiments in magnetic fields. Yet, contact-free optical me…
Evidence of Indium impurity band in superconducting (Sn,In)Te thin films
Jiashu Wang, Trisha Musall, Bo-An Chen +4
Sn1-xInxTe has been synthesized and studied recently as a candidate topological superconductor. Its superconducting critical temperature increases with Indium concentration. Howeve…
MBE growth of axion insulator candidate EuIn2As2
Muhsin Abdul Karim, Jiashu Wang, David Graf +6
The synthesis of thin films of magnetic topological materials is necessary to achieve novel quantized Hall effects and electrodynamic responses. EuIn2As2 is a recently predicted to…
Discovery of a high-temperature antiferromagnetic state and transport signatures of exchange interactions in a Bi2Se3/EuSe heterostructure
Ying Wang, Valeria Lauter, Olga Maximova +10
Spatial confinement of electronic topological surface states (TSS) in topological insulators poses a formidable challenge because TSS are protected by time-reversal symmetry. In pr…
Enhanced Dirac node separation in strained Cd3As2 topological semimetal
Gauthier Krizman, Joaquin Bermejo-Ortiz, Manik Goyal +7
In topological semimetals, nodes appear at symmetry points in the Brillouin zone as a result of band inversion, and yield quasi-relativistic massless fermions at low energies. Cd3A…
Energy gap of topological surface states in proximity to a magnetic insulator
Jiashu Wang, Tianyi Wang, Mykhaylo Ozerov +14
Topological surface-states can acquire an energy gap when time-reversal symmetry is broken by interfacing with a magnetic insulator. This gap has yet to be measured. Such topologic…
Observation of coexisting weak localization and superconducting fluctuations in strained Sn1-xInxTe thin films
Jiashu Wang, William Powers, Zhan Zhang +10
Topological superconductors have attracted tremendous excitement as they are predicted to host Majorana zero modes that can be utilized for topological quantum computing. Candidate…
