Multiferroic Quantum Criticality in a Proper Ferroelectric Quasi‐one‐dimensional Ising Antiferromagnet

Advanced Science, EarlyView.
Sr1−xBaxCo2V2O8 is established as a magnetic‐ion‐based proper displacive ferroelectric whose transition is continuously suppressed by Ba substitution to a ferroelectric quantum critical point. In the resulting quantum paraelectric regime, a transverse magnetic field induces magnetic quantum criticality, realizing multiferroic quantum criticality and ...

High temperature superconducting with two doping atoms in La-doped Bi-2201 and Y-doped Bi-2212 [PDF]

, 2009
These crystals have two doping patterns given by oxygen excess and doping with an additional atom with projected positions in theCuO2 plane. Both doping elements are necessary for the occurrence of superconductivity.

Uniaxial Strain‐Driven Ferroelastic Domain Tuning in LaAlO3${\rm LaAlO}_3$

Advanced Science, EarlyView.
The present work demonstrates based on AFM, μ$\umu$‐Raman spectroscopy, XRD, and first‐principles, that uniaxial strain provides a handle for tuning the ferroelastic domain populations in lanthanum aluminate, driving a continuous and controlled phase transition from a four‐variant rhombohedral crystal system to a two‐variant orthorhombic crystal system

Cr1/4NbSe2‐Single Crystal Growth and Evolution of Antiferromagnetic Correlated States

Advanced Science, EarlyView.
High‐quality single crystals Cr1/4NbSe2 were synthesized and comprehensively characterized for the first time. Advanced structural, electronic, and magnetic measurements uncover a correlated antiferromagnetic state, resolving longstanding inconsistencies regarding magnetic behavior derived from earlier polycrystal studies.

Hydrogen‐Bonding Order Associated With Radical Delocalization in Layered Organic Cathode Materials

Angewandte Chemie, EarlyView.
“TAQ” and TAPT share the same pyrazine‐based molecular structure but differ in degree of crystallinity. Combined x‐ray scattering, solid‐state NMR, MicroED, and EPR reveal that “TAQ”'s higher crystallinity and ordered hydrogen‐bonding network are associated with enhanced radical delocalization and conductivity, highlighting structural order as a design

Flat-band ratio and quantum metric in the superconductivity of modified Lieb lattices

Communications Physics
Flat bands may offer a route to high critical temperatures of superconductivity. It has been predicted that the quantum geometry of the bands as well as the ratio of the number of flat bands to the number of orbitals determine flat band superconductivity.

Observation of superconductivity in a nontrivial $${{{{\mathcal{Z}}}}}_{2}$$ Z 2 approximant quasicrystal

Communications Materials
Superconductivity and nontrivial topology are highly sought-after phenomena in quantum materials. While many topological crystalline materials have been found to exhibit superconductivity, their presence in quasicrystals—materials with a unique aperiodic
