Magnetic Dirac semimetal state of (Mn,Ge)BiTe
Alexander S. Frolov, Dmitry Yu. Usachov, Artem V. Tarasov +13
For quantum electronics, the possibility to finely tune the properties of magnetic topological insulators (TIs) is a key issue. We studied solid solutions between two isostructural…
Coexistence of bulk-nodal and surface-nodeless Cooper pairings in a superconducting Dirac semimetal
Xian P. Yang, Yigui Zhong, Sougata Mardanya +21
The interplay of nontrivial topology and superconductivity in condensed matter physics gives rise to exotic phenomena. However, materials are extremely rare where it is possible to…
Hidden spin-orbital texture at the -located valence band maximum of a transition metal dichalcogenide semiconductor
Oliver J. Clark, Oliver Dowinton, Mohammad Saeed Bahramy +1
Finding stimuli capable of driving an imbalance of spin-polarised electrons within a solid is the central challenge in the development of spintronic devices. However, without the a…

Epitaxial graphene/ferromagnetic metal (Gr/FM) heterostructures deposited onto heavy metals (HM) have been proposed for the realization of novel spintronic devices because of their…
Orbital-selective Band Hybridisation at the Charge Density Wave Transition in Monolayer TiTe
T. Antonelli, W. Rahim, M. D. Watson +12
An anomalous charge density wave (CDW) phase emerges in monolayer 1T-TiTe which is absent for the bulk compound, and whose origin is still poorly understood. Here,…
Emergence of Fermi arcs and novel magnetic splitting in an antiferromagnet
Benjamin Schrunk, Yevhen Kushnirenko, Brinda Kuthanazhi +14
The Fermi arcs are signatures of exotic states in solids because they defy conventional concept of Fermi surfaces as closed contours in momentum space. Fermi arcs were first discov…
Tuneable electron-magnon coupling of ferromagnetic surface states in PdCoO
Federico Mazzola, Chi-Ming Yim, Veronika Sunko +11
Controlling spin wave excitations in magnetic materials underpins the burgeoning field of magnonics. Yet, little is known about how magnons interact with the conduction electrons o…

We report a high-resolution angle-resolved photoemission (ARPES) study of the prototypical nearly-free-electron metal sodium. The observed mass enhancement is slightly smaller than…
Changes of Fermi Surface Topology due to the Rhombohedral Distortion in SnTe
Christopher D. O'Neill, Oliver J. Clark, Harry D. J. Keen +7
Stoichiometric SnTe is theoretically a small gap semiconductor that undergoes a ferroelectric distortion on cooling. In reality however, crystals are always non-stoichiometric and…
Electronically driven spin-reorientation transition of the correlated polar metal CaRuO
I. Marković, M. D. Watson, O. J. Clark +11
Polar distortions in solids give rise to the well-known functionality of switchable macroscopic polarisation in ferroelectrics and, when combined with strong spin-orbit coupling, c…

Probing spin correlations using angle resolved photoemission in a coupled metallic/Mott insulator system
V. Sunko, F. Mazzola, S. Kitamura +16
A nearly free electron metal and a Mott insulating state can be thought of as opposite ends of possibilities for the motion of electrons in a solid. In the magnetic oxide metal PdC…
