Evidence for an extended critical fluctuation region above the polar ordering transition in LiOsO
Jun-Yi Shan, A. de la Torre, N. J. Laurita +8
Metallic LiOsO undergoes a continuous ferroelectric-like structural phase transition below = 140 K to realize a polar metal. To understand the microscopic interactions th…
Cooperative Interactions Govern the Fermiology of the Polar Metal CaRuO
D. Puggioni, M. Horio, J. Chang +1
The antiferromagnetic Ruddlesden-Popper ruthenate CaRuO is a model polar metal, combining inversion symmetry breaking with metallic conductivity; however, its low tempe…
Magnetic Order Driven Ultrafast Phase Transition in NdNiO
V. Stoica, D. Puggioni, J. Zhang +12
Ultrashort x-ray pulses can be used to disentangle magnetic and structural dynamics and are accordingly utilized here to study the photoexcitation of NdNiO (NNO), a model nicke…
Evidence for the weakly coupled electron mechanism in an Anderson-Blount polar metal
N. J. Laurita, A. Ron, J. Shan +6
Over 50 years ago, Anderson and Blount proposed that ferroelectric-like structural phase transitions may occur in metals, despite the expected screening of the Coulomb interactions…
Ultrafast quasiparticle dynamics in correlated semimetal CaRuO
Yakun Yuan, Peter Kissin, Danilo Puggioni +7
The correlated polar semimetal CaRuO exhibits a rich phase diagram including two magnetic transitions (=56 K and =48 K) with the appearance of an insulating-l…
Crystal structure stability and electronic properties of layered nickelate LaNiO
Danilo Puggioni, James M. Rondinelli
We investigate the crystal structure and the electronic properties of the trilayer nickelate LaNiO by means of quantum mechanical calculations in the framework of th…
