Abstract Many large unit-cell rare-earth transition metal ternary alloys of the type Ra(M1−x M’ x )b exhibit non-monotonic ferrimagnetic Curie temperatures (T C) coupled to monotonic composition-controlled magnetization. Its origin remains an imp

Theoretical studies have predicted a Kondo effect driven charge density wave order with two sublattices characterized by different single-ion Kondo temperatures. Here, X-ray photoemission spectroscopy provides evidence of a dual Kondo effect in the c

Monolayer transition metal dechalcogenides are a promising platform to study the interplay of low-dimensionality and electron correlations. Here, the authors report a Mott insulator state in monolayer 1T-TaSe2, that survives far above room temperatur

Combination of low-dimensionality and electron correlation is vital for exotic quantum phenomena such as the Mott-insulating phase and high-temperature superconductivity. Transition-metal dichalcogenide (TMD) 1T-TaS2 has evoked great interest owing t

We study the electronic structure of single-crystal ${\mathrm{Tb}}_{0.5}{\mathrm{Sr}}_{0.5}{\mathrm{MnO}}_{3}$, a non-charge-ordered mixed-valent semiconductor which exhibits a glassy magnetic ground state. We use the techniques of soft x-ray photoem

We study the electronic structure of single crystal $1T\ensuremath{-}{\mathrm{TiSe}}_{2}$ using temperature ($T$)-dependent soft x-ray photoemission spectroscopy (PES) and natural circular dichroism (NCD) across the charge-density-wave (CDW) transiti

We study the electronic structure of GdNi and HoNi, which are magnetic materials with a Curie temperature ${T}_{c}=69$ and ${T}_{c}=36\phantom{\rule{0.28em}{0ex}}\mathrm{K}$, respectively. These materials are useful for magnetic refrigerator applicat

This study proposes a lattice model of a Fermi-Bose mixture with a composite hopping mechanism which swaps a boson and a fermion on nearest neighbor sites. The composite hopping causes unconventional superfluidity with coupled first-order insulator-m

We investigate and compare the electronic structure of a bulk single crystal of ${\mathrm{Y}}_{3}{\mathrm{Fe}}_{5}{\mathrm{O}}_{12}$ garnet [YIG, a high-${T}_{C}$ (= 560 K) ferrimagnet] with that of an epitaxial ultrathin (3.3 nm) film of YIG with a
