Utilizing frustration in Gd- and Yb-based oxides for milli-Kelvin adiabatic demagnetization refrigeration

Tim Treu, Marvin Klinger, Noah Oefele +3

The manifold of energetically degenerate configurations arising from competing interactions in frustrated magnets gives rise to an enhanced entropy at lowest temperatures, which ca…

Protracting the Weyl phase by a giant negative lattice expansion in Bi doped Sm $_{2}$ Ir $_{2}$ O $_{7}$

Prachi Telang, Surjeet Singh

We show that the Weyl phase in $S m_{2} I r_{2} O_{7}$ is protracted up to at least 2~\% alloying with Bi by an anomalous negative lattice expansion with $Δa \sim - 0.01$ Å. With furth…

Role of spin-phonon and electron-phonon interactions in phonon renormalization of (Eu $_{1 - x}$ Bi $_{x}$ ) $_{2}$ Ir $_{2}$ O $_{7}$ across the metal-insulator phase transition: Temperature-dependent Raman and X-ray studies

Anoop Thomas, Prachi Telang, Kshiti Mishra +5

We report temperature-dependent Raman scattering and X-ray diffraction studies of pyrochlore iridates, (Eu $_{1 - x}$ Bi $_{x}$ ) $_{2}$ Ir $_{2}$ O $_{7}$ , for x=0, 0.02, 0.035, 0.05 and 0.1. The te…

Insulator-to-metal transition in the pyrochlore iridates series (Eu_1-xBi_x)2Ir2O7 probed using Hard X-ray Photoemission Spectroscopy

Prachi Telang, Kshiti Mishra, Rabindranath Bag +3

Eu2Ir2O7, a candidate Weyl semimetal, shows an insulator-to-metal transition as a function of Bi substitution at the Eu site. In this work, we investigate the (Eu_1-xBi_x)2Ir2O7 se…

Ultrafast melting and recovery of collective order in the excitonic insulator Ta $_{2}$ NiSe $_{5}$

Hope M. Bretscher, Paolo Andrich, Prachi Telang +4

The layered chalcogenide Ta $_{2}$ NiSe $_{5}$ has been proposed to host an excitonic condensate in its ground state, a phase that could offer a unique platform to study and manipulat…

Monopole-limited nucleation of magnetism in Eu $_{2}$ Ir $_{2}$ O $_{7}$

Giacomo Prando, Prachi Telang, Stephen D. Wilson +2

We present an in-depth analysis of muon-spin spectroscopy measurements of Eu $_{2}$ Ir $_{2}$ O $_{7}$ under the effect of the Eu $_{1 - x}$ Bi $_{x}$ isovalent and diamagnetic substitution…

Imaging the coherent propagation of collective modes in the excitonic insulator candidate Ta $_{2}$ NiSe $_{5}$ at room temperature

Hope M. Bretscher, Paolo Andrich, Yuta Murakami +10

Excitonic insulators host a condensate of electron-hole pairs at equilibrium, giving rise to collective many-body effects. Although several materials have emerged as excitonic insu…

Anomalous lattice contraction and emergent electronic phases in Bi-doped Eu $_{2}$ Ir $_{2}$ O $_{7}$

Prachi Telang, Kshiti Mishra, Giacomo Prando +2

We study the pyrochlore series (Eu $_{1 - x}$ Bi $_{x}$ ) $_{2}$ Ir $_{2}$ O $_{7}$ for $0 \leq x \leq 1$ . We show that for small $x$ , the lattice undergoes an anomalous contraction but the all-in/a…

Dilute stuffing in the pyrochlore iridate $E u_{2} I r_{2} O_{7}$

Prachi Telang, Kshiti Mishra, A. K. Sood +1

The pyrochlore Eu $_{2}$ Ir $_{2}$ O $_{7}$ has recently attracted significant attention as a candidate Weyl semimetal. The previous reports on this compound unanimously show a thermally indu…
