Giant lattice softening at a Lifshitz transition in SrRuO
Hilary M. L. Noad, Kousuke Ishida, You-Sheng Li +11
The interplay of electronic and structural degrees of freedom in solids is a topic of intense research. Experience and intuition suggest that structural changes drive conduction el…
Hierarchy of Lifshitz transitions in the surface electronic structure of SrRuO under uniaxial compression
Edgar Abarca Morales, Gesa-R. Siemann, Andela Zivanovic +12
We report the evolution of the electronic structure at the surface of the layered perovskite SrRuO under large in-plane uniaxial compression, leading to anisotropic $B_{1g}…
Probing momentum-dependent scattering in uniaxially stressed SrRuO through the Hall effect
Po-Ya Yang, Hilary M. L. Noad, Mark E. Barber +4
Under in-plane uniaxial stress, the largest Fermi surface sheet of the correlated metal SrRuO undergoes a Lifshitz transition from an electron-like to an open geometry. We…
Spin-density-wave order controlled by uniaxial stress in CeAuSb
R. Waite, F. Orlandi, D. A. Sokolov +6
The tetragonal heavy-fermion compound CeAuSb (space group ) exhibits incommensurate spin density wave (SDW) order below with the propagation vector…
Heisenberg spins on an anisotropic triangular lattice: PdCrO2 under uniaxial stress
Dan Sun, Dmitry A. Sokolov, Richard Waite +6
When Heisenberg spins interact antiferromagnetically on a triangular lattice and nearest-neighbor interactions dominate, the ground state is 120 antiferromagnetism. In th…

Aaron Chronister, Manuel Zingl, Andrej Pustogow +10
We perform nuclear magnetic resonance (NMR) measurements of the oxygen-17 Knight shifts for SrRuO, while subjected to uniaxial stress applied along [100] direction. The res…
The planar triangular magnet AgCrSe: magnetic frustration, short range correlations, and field tuned anisotropic cycloidal magnetic order
M. Baenitz, M. M. Piva, S. Luther +25
Our studies evidence an anisotropic magnetic order below ~K. Susceptibility data in small fields of about 1~T reveal an antiferromagnetic (AFM) order for , whe…
Magnetic field-induced softening of spin waves and hard-axis order in Kondo-lattice ferromagnet CeAgSb
S. E. Nikitin, A. Podlesnyak, J. Xu +5
A significant number of Kondo-lattice ferromagnets order perpendicular to the easy magnetization axis dictated by the crystalline electric field. The nature of this phenomenon has…
Changes of Fermi Surface Topology due to the Rhombohedral Distortion in SnTe
Christopher D. O'Neill, Oliver J. Clark, Harry D. J. Keen +7
Stoichiometric SnTe is theoretically a small gap semiconductor that undergoes a ferroelectric distortion on cooling. In reality however, crystals are always non-stoichiometric and…
Electronically driven spin-reorientation transition of the correlated polar metal CaRuO
I. Marković, M. D. Watson, O. J. Clark +11
Polar distortions in solids give rise to the well-known functionality of switchable macroscopic polarisation in ferroelectrics and, when combined with strong spin-orbit coupling, c…
A key role of correlation effects in the Lifshitz transition in SrRuO
Mark E. Barber, Frank Lechermann, Sergey V. Streltsov +8
Uniaxial pressure applied along an Ru-Ru bond direction induces an elliptical distortion of the largest Fermi surface of SrRuO, eventually causing a Fermi surface topologic…
Magnetic frustration and spontaneous rotational symmetry breaking in PdCrO2
Dan Sun, Dmitry Sokolov, Jack Bartlett +8
In the triangular layered magnet PdCrO2 the intralayer magnetic interactions are strong, however the lattice structure frustrates interlayer interactions. In spite of this, long-ra…
