Collapse of Jahn-Teller Phonons in La $_{1 - x}$ Sr $_{x}$ MnO $_{3}$ with Weak Magnetoresistance

Tyler C. Sterling, Andrei T. Savici, Ryoichi Kajimoto +4

Perovskite manganites are quantum materials exhibiting competing interactions inducing colossal magnetoresistance (CMR). The prevailing theory of CMR highlights the essential role…

Phonons reflect dynamic spin-state order in LaCoO $_{3}$

Alsu Ivashko, Taishun Manjo, Maximilian Kauth +17

We investigate lattice dynamics in LaCoO $_{3}$ using inelastic neutron and x-ray scattering over $T = 2\mbox{-}650\,\mathrm{K}$, spanning the spin-state crossover at $T_{1} \approx 1…

Soft phonon and the central peak at the cubic-to-tetragonal phase transition in SrTiO $_{3}$

Avishek Maity, Klaus Habicht, Michael Merz +8

The continuous displacive phase transition in SrTiO $_{3}$ near $T_{c} \approx 105$ K features a central elastic peak in neutron scattering investigations at temperatures above $T_{c}$ , i…

Charge-density-wave quantum critical point under pressure in 2 $H$ -TaSe $_{2}$

Yuliia Tymoshenko, Amir-Abbas Haghighirad, Rolf Heid +13

Suppressing of an ordered state that competes with superconductivity is one route to enhance superconducting transition temperatures. Whereas the effect of suppressing magnetic sta…
