Twisting in bilayers introduces structural chirality with two enantiomers, i.e., left- and right-hand bilayers, depending on the oriented twist angle. The interplay between this global chirality and additional degrees of freedom, such as magnetic ord

We present a combined polarized neutron and x-ray scattering study on two enantiopure langasite single crystals aimed at the determination of their absolute structural and magnetic chiralities and the coupling between them. Our respective data sets u

Using micromagnetic simulations, we have modelled the formation of imprinted merons and anti-merons in cobalt overlayers of different thickness (1-8 nm), stabilised by interfacial exchange with antiferromagnetic vortices in $\alpha$-Fe2O3. Structures

The magnetic transitions in La1-xCaxMnO3 (x=0.25, 0.50) were studied by synchrotron x-ray and neutron powder diffraction. For x=0.25 the large V=0.13% at TC is due to the simultaneous insulator-to-metal transition. For x=0.50 below TC we observed a d

Neutron powder diffraction and ac susceptibility data on a series of ErBa2Cu3O6+x samples prepared to achieve thermal equilibrium at low temperature provide evidence of structural inhomogeneities near the tetragonal-to- orthorhombic (T'O) transition.

The defect structure of oxygenated and reduced Nd2CuOy (y4) was investigated by single-crystal neutron diffraction. Structural refinements indicate the presence of interstitial oxygen atoms in the apical O(3) position, directly above or below the cop

We have measured the superconducting and normal tunneling characteristics of quality controlled planar junctions based on YBa2Cu4O8 (Y124) single crystals. Our data show that the in-plane properties are similar to the YBa2Cu3O7 (Y123) system. A highe

Charge localization by static and dynamic distortions of the MnO6 octahedra in perovskite manganites
We present transport and neutron-diffraction data establishing a clear link between static and dynamic distortions of the MnO6 octahedra and charge mobility in Al-xA′x MnO3 (A= La or Pr; A′ = Ca or Sr). Systematic analysis of the Mn-O bond length
