Reversible Non-Volatile Electronic Switching in a Near Room Temperature van der Waals Ferromagnet
Han Wu, Lei Chen, Paul Malinowski +37
The ability to reversibly toggle between two distinct states in a non-volatile method is important for information storage applications. Such devices have been realized for phase-c…
Thermal cycling induced alteration of the stacking order and spin-flip in the room temperature van der Waals magnet FeGeTe
Xiang Chen, Wei Tian, Yu He +6
The magnetic properties of the quasi-two-dimensional van der Waals magnet FeGeTe (F5GT), which has a high ferromagnetic ordering temperature 315 K…
Bond Ordering and Molecular Spin-Orbital Fluctuations in the Cluster Mott Insulator GaTaSe
Tsung-Han Yang, S. Kawamoto, Tomoya Higo +8
For materials where spin-orbit coupling is competitive with electronic correlations, the spatially anisotropic spin-orbital wavefunctions can stabilize degenerate states that lead…
Role of electron-phonon coupling in excitonic insulator candidate Ta2NiSe5
Cheng Chen, Xiang Chen, Weichen Tang +15
Electron-hole bound pairs, or excitons, are common excitations in semiconductors. They can spontaneously form and ``condense'' into a new insulating ground state -- the so-called e…
Magnetic excitations in double perovskite iridates LaIrO ( = Co, Ni, and Zn) mediated by 3-5 hybridization
Wentao Jin, Sae Hwan Chun, Jungho Kim +6
By performing resonant inelastic x-ray scattering (RIXS) measurements at the Ir edge, we have investigated the low-energy elementary excitations in a seri…
Synthesis, physical and magnetic properties of CuAlCrS: a new Cr-based breathing pyrochlore
S. Sharma, M. Pocrnic, B. N. Richtik +10
We present the synthesis and physical properties of a new breathing pyrochlore magnet CuAlCrS with the help of synchrotron x-ray diffraction (XRD), magnetization under ambi…
Structural and Magnetic Transitions in the Planar Antiferromagnet BaIrO
Xiang Chen, Yu He, Shan Wu +7
We report the structural and magnetic ground state properties of the monoclinic compound barium iridium oxide BaIrO using a combination of resonant x-ray scattering,…
Structural, electronic, and magnetic properties of nearly-ideal 1/2 iridium halides
D. Reig-i-Plessis, T. A. Johnson, K. Lu +9
Heavy transition metal magnets with 1/2 electronic ground states have attracted recent interest due to their penchant for hosting new classes of quantum spin liqu…
Divergence of the quadrupole-strain susceptibility of YbRuGe; a local moment realization of electronic nematicity
Elliott Rosenberg, Jiun-Haw Chu, Jacob Ruff +2
Ferroquadrupole order associated with local atomic orbitals of rare earth ions is a realization of electronic nematic order. However, there are relatively few examples of inte…
Emergence of coherence in the charge-density wave state of 2H-NbSe
U. Chatterjee, J. Zhao, M. Iavarone +15
A charge-density wave (CDW) state has a broken symmetry described by a complex order parameter with an amplitude and a phase. The conventional view, based on clean, weak-coupling s…
Susceptibility anisotropy in an iron arsenide superconductor revealed by x-ray diffraction in pulsed magnetic fields
J. P. C. Ruff, J. -H. Chu, H. -H. Kuo +4
In addition to unconventional high-Tc superconductivity, the iron arsenides exhibit strong magnetoelastic coupling and a notable electronic anisotropy within the a-b plane. We rela…
Definitive Evidence for Order-by-Quantum-Disorder in Er2Ti2O7
Lucile Savary, Kate A. Ross, Bruce D. Gaulin +2
Here we establish the systematic existence of a U(1) degeneracy of all symmetry-allowed Hamiltonians quadratic in the spins on the pyrochlore lattice, at the mean-field level. By e…
A robust but disordered collapsed-volume phase in a cerium alloy under the application of pulsed magnetic fields
