Realizing Magnetoelectric Coupling with Hydroxide as a Knob
J. Y. Ni, P. S. Wang, J. L. Lu +1
Materials with a coexistence of magnetic and ferroelectric order (i.e., multiferroics) provide an efficient route for the control of magnetism by electric fields. Unfortunately, a…
Mermin-Wagner physics, (H,T) phase diagram, and candidate quantum spin-liquid phase in the spin-1/2 triangular-lattice antiferromagnet Ba8CoNb6O24
Y. Cui, J. Dai, P. Zhou +11
BaCoNbO presents a system whose Co ions have an effective spin 1/2 and construct a regular triangular-lattice antiferromagnet (TLAFM) with a very large interl…
Robust short-range-ordered nematicity in FeSe evidenced by high-pressure NMR
P. S. Wang, P. Zhou, S. S. Sun +5
We report high-pressure Se NMR studies on FeSe single crystals that reveal a prominent inhomogeneous NMR linewidth broadening upon cooling, with the magnetic field applied a…
Experimental Approach to the Thermodynamics of the Pure Two-Dimensional Spin-1/2 Triangular Lattice Antiferromagnet in Ba8CoNb6O24
Y. Cui, J. Dai, P. Zhou +10
Frustrated quantum magnets pose well-defined questions concerning quantum fluctuation effects and the nature of the many-body wavefunction, which challenge theory, numerics, experi…
Pressure Induced Stripe-order Antiferromagnetism and First-order Phase Transition in FeSe
P. S. Wang, S. S. Sun, Y. Cui +5
To elucidate the magnetic structure and the origin of the nematicity in FeSe, we perform a high-pressure Se NMR study on FeSe single crystals. We find a suppression of the s…
Spin-Fluctuation-Induced Non-Fermi-Liquid Behavior with suppressed superconductivity in LiFeCoAs
Y. M. Dai, H. Miao, L. Y. Xing +12
A series of LiFeCoAs compounds with different Co concentrations have been studied by transport, optical spectroscopy, angle-resolved photoemission spectroscopy and nu…
Nearly-critical spin and charge fluctuations in KFe2As2 observed by high-pressure NMR
P. S. Wang, P. Zhou, J. Dai +7
We report a high-pressure 75As NMR study on the heavily hole-doped iron pnictide superconductor KFe2As2 (Tc~3.8 K). The low-energy spin fluctuations are found to decrease with appl…
Predicting a Ferrimagnetic Phase of Zn2FeOsO6 with Strong Magnetoelectric Coupling
P. S. Wang, W. Ren, L. Bellaiche +1
Multiferroic materials, in which ferroelectric and magnetic ordering coexist, are of fundamental interest for the development of novel memory devices that allow for electrical writ…
Phase Separation, Competition, and Volume Fraction Control in NaFeCoAs
Long Ma, J. Dai, P. S. Wang +9
We report a detailed nuclear magnetic resonance (NMR) study by combined Na and As measurements over a broad range of doping to map the phase diagram of NaFeCo…
Room-Temperature Ferrimagnet with Frustrated Antiferroelectricity: Promising Candidate Toward Multiple State Memory
P. S. Wang, H. J. Xiang
On the basis of first-principles calculations we show that the M-type hexaferrite BaFe12O19 exhibits frustrated antiferroelectricity associated with its trigonal bipyramidal Fe3+ s…
Simultaneous optimization of spin fluctuations and superconductivity under pressure in an iron-based superconductor
G. F. Ji, J. S. Zhang, Long Ma +9
We present a high-pressure NMR study of the overdoped iron pnictide superconductor NaFeCoAs. The low-energy antiferromagnetic spin fluctuations in the normal stat…
Orbital selective correlations between nesting/scattering/Lifshitz transition and the superconductivity in AFe1-xCoxAs (A=Li, Na)
Z. R. Ye, Y. Zhang, M. Xu +9
The correlations between the superconductivity in iron pnictides and their electronic structures are elusive and controversial so far. Here through angle-resolved photoemission spe…
Unified Model of Ferroelectricity Induced by Spin Order
H. J. Xiang, P. S. Wang, M. -H. Whangbo +1
The ferroelectricity of multiferroics induced by spin order is commonly explained by considering either purely electronic or ion-displacement contribution. However, there is no gen…
