Strongly correlated superconductivity in a copper-based metal-organic framework with a perfect kagome lattice
T. Takenaka, K. Ishihara, M. Roppongi +17
Metal-organic frameworks (MOFs), which are self-assemblies of metal ions and organic ligands, provide a tunable platform to search a new state of matter. A two-dimensional (2D) per…
Direct Observation of Magnon Modes in Kagome Artificial Spin Ice with Topological Defects
V. S. Bhat, S. Watanabe, K. Baumgaertl +1
We investigate spin dynamics of artificial spin ice (ASI) where topological defects confine magnon modes in NiFe nanomagnets arranged on an interconnected kagome latt…
Coincidence of magnetic and valence quantum critical points in CeRhIn5 under pressure
Z. Ren, G. W. Scheerer, D. Aoki +3
We present accurate electrical resistivity measurements along the two principle crystallographic axes of the pressure-induced heavy-fermion superconductor CeRhIn5 up to 5.63 GPa. F…
Femtosecond core level photoemision spectroscopy on 1T-TaS2 using 60 eV laser source
K. Ishizaka, T. Kiss, T. Yamamoto +11
Time-resolved photoelectron spectroscopy (trPES) can directly detect transient electronic structure, thus bringing out its promising potential to clarify nonequilibrium processes a…
Superconducting electronic state in optimally doped YBa2Cu3O7-d observed with laser-excited angle-resolved photoemission spectroscopy
M. Okawa, K. Ishizaka, H. Uchiyama +9
Low energy electronic structure of optimally doped YBa2Cu3O7-d is investigated using laser-excited angle-resolved photoemission spectroscopy. The surface state and the CuO chain ba…
Bulk electronic structure of the antiferromagnetic superconducting phase in ErNi2B2C
T. Baba, T. Yokoya, S. Tsuda +15
We have performed temperature (T) - dependent laser-photoemission spectroscopy of antiferromagnetic (AF) superconductor ErNi2B2C to study the electronic-structure evolution reflect…
