Open AccessSoftening of a flat phonon mode in the kagome ScV6Sn6
Geometrically frustrated kagome lattices are raising as novel platforms to engineer correlated topological electron flat bands that are prominent to electronic instabilities. Here, we demonstrate a phonon soft...

Open AccessSignature of spin-phonon coupling driven charge density wave in a kagome magnet
The intertwining between spin, charge, and lattice degrees of freedom can give rise to unusual macroscopic quantum states, including high-temperature superconductivity and quantum anomalous Hall effects. Recen...

Open AccessEndless Dirac nodal lines in kagome-metal Ni3In2S2
Topological semimetals are a frontier of quantum materials. In multiband electronic systems, topological band crossings can form closed curves, known as nodal lines. In the presence of spin–orbit coupling and/...

Open AccessCharge density waves in cuprate superconductors beyond the critical do**
The unconventional normal-state properties of the cuprates are often discussed in terms of emergent electronic order that onsets below a putative critical do** of xc ≈ 0.19. Charge density wave (CDW) correlatio...

The Spin Polarized Band Structure of Strained Thin Films of Gadolinium
The magnetic properties of strained thin films of gadolinium are characterized by a wave vector and thickness dependence of the exchange splitting. The spin-resolved band structure has been mapped by spin pola...

Direct evidence for a half-metallic ferromagnet
Half-metallic materials are characterized by the coexistence of metallic behaviour for one electron spin and insulating behaviour for the other. Thus, the electronic density of states is completely spin polari...

Low energy electron oscillations during epitaxial growth of thin films
We have measured the specularly reflected intensity of low energy (12 eV) electrons as a function of the deposition time during the growth of Cu-thin films on fcc-Co(100) and Co-thin films on Cu(100). The meas...

Covalency in the electronic structure of Fe3O4: An ultraviolet inverse photoemission investigation
The unoccupied electronic structure of an opend-shell transition metal oxide, namely Fe3O4, has been addressed by measuring ultraviolet angle-integrated inverse photoemission (IP) spectra acquired in the isochrom...
