Detection of Weyl Fermions and the Metal to Weyl-Semimetal phase transition in WTe via broadband High Resolution NMR
Wassilios Papawassiliou, José P. Carvalho, Hae Jin Kim +11
Weyl Fermions (WFs) in the type-II Weyl Semimetal (WSM) WTe are difficult to resolve experimentally because the Weyl bands disperse in an extremely narrow region of the (E-k) s…
Direct observation of Dirac states in Bi2Te3 nanoplatelets by 125Te NMR
Wassilios Papawassiliou, Aleksander Jaworski, Andrew J. Pell +12
Detection of the metallic Dirac electronic states on the surface of Topological Insulators (TIs) is a tribune for a small number of experimental techniques the most prominent of wh…
Nuclear Magnetic Resonance as a probe of nanometre-size orbital textures in magnetic transition metal oxides
G. Papavassiliou, M. Pissas, M. Belesi +7
The study of strong electron correlations in transition metal oxides with modern microscopy and diffraction techniques unveiled a fascinating world of nanosize textures in the spin…
Spin-polarized oxygen hole states in cation deficient La(1-x)CaxMnO(3+delta)
G. Papavassiliou, M. Pissas, M. Belesi +5
When holes are doped into a Mott-Hubbard type insulator, like lightly doped manganites of the La(1-x)CaxMnO3 family, the cooperative Jahn-Teller distortions and the appearance of o…
Orbital domain state and finite size scaling in ferromagnetic insulating manganites
G. Papavassiliou, M. Belesi, M. Fardis +4
55Mn and 139La NMR measurements on a high quality single crystal of ferromagnetic (FM) La0.80Ca20MnO3 demonstrate the formation of localized Mn(3+,4+) states below 70 K, accompanie…
B and Al NMR spin-lattice relaxation and Knight shift study of MgAlB. Evidence for anisotropic Fermi surface
G. Papavassiliou, M. Pissas, M. Karayanni +3
We report a detailed study of B and Al NMR spin-lattice relaxation rates (), as well as of Al Knight shift (K) of MgAlB, …
