Papers
Metal-rich Au-silicide nanoparticles for use in nanotechnology
Eric Moyen,Magali Macé,Guillaume Agnus,Antoine Fleurence,T. Maroutian,F. Houzé,Andrzej Stupakiewicz,Laurence Masson,Bernard Bartenlian,Wulf Wulfhekel,Pierre Beauvillain,Margrit Hanbücken +11 more
TL;DR: In this paper, the Stranski-Krastanov growth mode of the Au-Si(111) system is exploited to functionalize chemically and magnetically silicon surfaces by local passivation.
Dynamic magnetic excitations in 3d and 4f atoms and clusters
Timofey Balashov,Toshio Miyamachi,Toshio Miyamachi,T. Schuh,Tobias Märkl,Christopher Bresch,Wulf Wulfhekel +6 more
TL;DR: In this paper, the magnetic anisotropic properties of rare earth metal atoms were investigated and the authors showed that the spin flips of a tunneling electron provided by a scanning tunneling microscope may be flipped and angular momentum is transferred to the magnetic system.
Spin-Polarized Scanning Tunneling Microscopy of Magnetic Structures and Antiferromagnetic Thin Films
Wulf Wulfhekel,Jürgen Kirschner +1 more
TL;DR: The spin-polarized scanning tunneling microscopy (Sp-STM) as discussed by the authors has been used for high-resolution magnetic imaging, which is related to the magnetic configuration of the sample.
Emergence of Nontrivial Low‐Energy Dirac Fermions in Antiferromagnetic EuCd2As2
Junzhang Ma,Junzhang Ma,Han Wang,Simin Nie,Changjiang Yi,Yuanfeng Xu,Hang Li,Jasmin Jandke,Wulf Wulfhekel,Yaobo Huang,Damien West,Pierre Richard,Pierre Richard,Alla Chikina,Vladimir N. Strocov,Joël Mesot,Joël Mesot,Hongming Weng,Shengbai Zhang,Youguo Shi,Tian Qian,Ming Shi,Hong Ding +22 more
TL;DR: It is ascertained that band inversion induces a topologically nontrivial ground state in EuCd2 As2 , and ideal magnetic Dirac fermions with simplest double cone structure near the Fermi level emerge in the antiferromagnetic (AFM) phase.
Direct Probing of a Large Spin-Orbit Coupling in the FeSe Superconducting Monolayer on STO.
TL;DR: In this paper , the spin-orbit coupling in a two-dimensional high-temperature superconductor using electrons is investigated and it is shown that the scattering cross-section is spin dependent.
