Autor: Tommaso Antonelli, Warda Rahim, Matthew D. Watson, Akhil Rajan, Oliver J. Clark, Alisa Danilenko, Kaycee Underwood, Igor Marković, Edgar Abarca-Morales, Seán R. Kavanagh, P. Le Fèvre, F. Bertran, K. Rossnagel, David O. Scanlon, Phil D. C. King

Publikováno v: npj Quantum Materials, Vol 7, Iss 1, Pp 1-10 (2022)

Abstract Reducing the thickness of a material to its two-dimensional (2D) limit can have dramatic consequences for its collective electronic states, including magnetism, superconductivity, and charge and spin ordering. An extreme case is TiTe2, where

Spin‐Momentum Locking and Ultrafast Spin‐Charge Conversion in Ultrathin Epitaxial Bi1 − xSbx Topological Insulator

Autor: E. Rongione, L. Baringthon, D. She, G. Patriarche, R. Lebrun, A. Lemaître, M. Morassi, N. Reyren, M. Mičica, J. Mangeney, J. Tignon, F. Bertran, S. Dhillon, P. Le Févre, H. Jaffrès, J.‐M. George

Publikováno v: Advanced Science, Vol 10, Iss 19, Pp n/a-n/a (2023)

Abstract The helicity of three‐dimensional (3D) topological insulator surface states has drawn significant attention in spintronics owing to spin‐momentum locking where the carriers' spin is oriented perpendicular to their momentum. This property

Electronic reconstruction forming a C 2-symmetric Dirac semimetal in Ca3Ru2O7

Publikováno v: npj Quantum Materials, Vol 6, Iss 1, Pp 1-7 (2021)

Abstract Electronic band structures in solids stem from a periodic potential reflecting the structure of either the crystal lattice or electronic order. In the stoichiometric ruthenate Ca3Ru2O7, numerous Fermi surface-sensitive probes indicate a low-

Weyl-like points from band inversions of spin-polarised surface states in NbGeSb

Autor: I. Marković, C. A. Hooley, O. J. Clark, F. Mazzola, M. D. Watson, J. M. Riley, K. Volckaert, K. Underwood, M. S. Dyer, P. A. E. Murgatroyd, K. J. Murphy, P. Le Fèvre, F. Bertran, J. Fujii, I. Vobornik, S. Wu, T. Okuda, J. Alaria, P. D. C. King

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-8 (2019)

Bulk band inversions in solids may unlock topological surface phenomena and symmetry-protected states. Here, the authors generate a surface state band inversion in the nonsymmorphic semimetal NbGeSb, leading to protected crossing points in the result

Effect of the valence state on the band magnetocrystalline anisotropy in two-dimensional rare-earth/noble-metal compounds

Autor: M. Blanco-Rey, R. Castrillo-Bodero, K. Ali, P. Gargiani, F. Bertran, P. M. Sheverdyaeva, J. E. Ortega, L. Fernandez, F. Schiller

Publikováno v: Physical Review Research, Vol 4, Iss 1, p 013237 (2022)

In intermetallic compounds with zero orbital momentum (L=0) the magnetic anisotropy and the electronic band structure are interconnected. Here, we investigate this connection in divalent Eu and trivalent Gd intermetallic compounds. We find by x-ray m

Entanglement and manipulation of the magnetic and spin–orbit order in multiferroic Rashba semiconductors

Autor: J. Krempaský, S. Muff, F. Bisti, M. Fanciulli, H. Volfová, A. P. Weber, N. Pilet, P. Warnicke, H. Ebert, J. Braun, F. Bertran, V. V. Volobuev, J. Minár, G. Springholz, J. H. Dil, V. N. Strocov

Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-7 (2016)

Inα-GeTe, ferroelectric polarization acts to break inversion symmetry of the lattice and induce a strong Rashba-type spin splitting of the electronic band structure. Here, the authors study how this effect competes with Zeeman splitting due to ferro

Once doped away from their parent Mott insulating state, the hole-doped cuprates enter into many varied and exotic phases. The onset temperature of each phase is then plotted versus p-the number of doped holes per copper atom - to form a representati
