Direct observation of competition between superconductivity and charge density wave order in YBa2Cu3O6.67
X-ray diffraction experiments reveal that spatial charge ordering occurs in the pseudogap state of YBa2Cu3O6.67. Moreover, this charge ordered state competes with high-temperature superconductivity,
Competing charge, spin, and superconducting orders in underdoped YBa2Cu3Oy
To explore the doping dependence of the recently discovered charge-density-wave (CDW) order in YBa2Cu3Oy, we present a bulk-sensitive high-energy x-ray study for several oxygen concentrations,
Stripe Order in Superconducting La2−xBaxCuO4 (0.095 x 0.155)
The correlations between stripe order, superconductivity, and crystal structure in La{sub 2-x}Ba{sub x}CuO{sub 4} single crystals have been studied by means of x-ray and neutron diffraction as well
Magnetic field controlled charge density wave coupling in underdoped YBa2Cu3O6+x
An X-ray study of the high-field charge density wave (CDW) in YBCO finds that the mirror symmetry of individual bilayers is broken by the CDW at low and high fields, allowing Fermi surface reconstruction, as recently suggested.
Oriented attachment and exchange coupling of α-Fe2O3 nanoparticles
(07/03/2019) Oriented attachment and exchange coupling of α-Fe2O3 nanoparticles We show that antiferromagnetic nanoparticles of alpha-Fe2O3 (hematite) under wet conditions can attach into chains
Field-Induced Linear Magnetoelastic Coupling in Multiferroic TbMnO3
We have used in-field neutron and x-ray single-crystal diffraction to measure the incommensurability {delta} of the crystal and magnetic structures of multiferroic TbMnO{sub 3}. We show that the flop
Evidence for unusual superconducting correlations coexisting with stripe order in La 1.875 Ba 0.125 CuO 4
We present new x-ray and neutron-scattering measurements of stripe order in ${\text{La}}_{1.875}{\text{Ba}}_{0.125}{\text{CuO}}_{4}$, along with low-field susceptibility, thermal conductivity, and
Spontaneous symmetry breaking by charge stripes in the high pressure phase of superconducting La1.875Ba0.125CuO4.
Pressure is used to restore the average fourfold symmetry in a single crystal of La1.875Ba0.125CuO4, and it is shown by x-ray diffraction that charge-stripe order still occurs, and that electronically driven stripe order can spontaneously break the lattice symmetry.
Enhanced charge stripe order of superconducting La(2-x)Ba(x)CuO(4) in a magnetic field
The effect of a magnetic field on the charge stripe order in La(2-x)Ba(x)CuO(4) has been studied by means of high energy (100 keV) x-ray diffraction for charge carrier concentrations ranging from
