The spin-orbit exciton (SOE) in iridates is a propagating quasiparticle whose dispersion in a Mott insulator directly reflects the underlying antiferromagnetic (AF) order. The Ruddlesden-Popper iridates Srₙ₊₁IrₙO₃ₙ₊₁ evolve from the Jeff = ½ AF insulators Sr₂IrO₄ and Sr₃Ir₂O₇ to the semimetallic perovskite SrIrO₃, with an insulator-metal transition (IMT) governed by strong spin-orbit coupling,...

Soft X-ray microscopy combines high spatial resolution with sensitivity to the chemical composition, electronic structure, and magnetic properties of materials. By tuning the photon energy across characteristic absorption edges, it becomes possible to visualize the spatial distribution of different elements and their chemical states, providing valuable insights into the structure and...

Quantum materials are a broad class of solids whose properties emerge from quantum-mechanical and collective electronic effects that have no classical counterpart, superconductivity being one of the best-known examples. Non-trivial band topology gives rise to further exotic phenomena, such as robust spin-polarized surface states, making these materials highly attractive for spintronics and...

Ferroelectric topological materials combining ferroelectricity and non-trivial band topology open promising frontiers in topological matter by introducing ferroelectric-driven inversion symmetry breaking in the system [1-3]. In particular, ferroelectricity in topological crystalline insulator has been predicted to support the emergence of inversion breaking Weyl semimetal phase, which so far...

Zirconia-based materials are widely used in optical, energy-related, and functional ceramic applications owing to their excellent mechanical, thermal, dielectric, and chemical stability. Their properties can be tailored through stabilization with aliovalent dopants, including luminescent rare-earth (Eu, Yb, Gd) and transition-metal (Mn, Cu) ions. Such modifications affect phase composition,...

Small-angle neutron scattering (SANS) is a versatile technique for investigating structural features and spatial correlations in materials over length scales typically ranging from approximately 1 to 100 nm, with the accessible range depending on the instrument configuration. By probing variations in neutron scattering length density, SANS provides insight into nanoscale structures in a wide...

Presentation aims to give a very brief introduction into neutron spectroscopy. Inelastic neutron scattering probes the dynamics of materials by measuring the energy exchanged between neutrons and a sample during scattering. This allows access to a wide range of phenomena, including atomic diffusion, molecular rotations and vibrations, phonons, magnons, crystal-field excitations, and other...

Fast-neutron imaging offers unique capabilities for the nondestructive investigation of dense and compositionally heterogeneous objects, particularly those containing both light and heavy elements. However, its wider application is limited by the efficiency of existing detection technologies. Conventional scintillator screens typically combine hydrogen-rich polypropylene (PP) with luminescent...
