Tunable magnetic anisotropy of antiferromagnetic NiO in (Fe)/NiO/MgO/Cr/MgO(001) epitaxial multilayers.

Tunable magnetic anisotropy of antiferromagnetic NiO in (Fe)/NiO/MgO/Cr/MgO(001) epitaxial multilayers.

27.07.2023
We report on the magnetic properties of antiferromagnetic NiO(001) thin films in epitaxially grown (Fe)/NiO/MgO(dMgO)/Cr/MgO(001) system for different thicknesses of MgO, dMgO. Results of X‑ray Magnetic Linear Dichroism (XMLD) show that together with an increase of dMgO, rotation of NiO spins from in‑plane towards out‑of‑plane direction occurs. Furthermore, we proved the existence of a multidomain state in NiO as a result of competition between the ferromagnet/antiferromagnet exchange coupling and strain exerted on the NiO by the MgO buffer layer.

Structural insights into innate immune evasion in human-infective African trypanosomes

Structural insights into innate immune evasion in human-infective African trypanosomes

21.06.2023
Researchers from Sebastian Zoll's group at IOCB Prague determined the cryo-EM structures of a surface protein that helps human-infective trypanosomes to evade the alternative pathway of the innate immune response.

Research on two-dimensional electron gas (2DEG) formed on a tellurium-passivated InAs(110) surface

12.06.2023
Researchers from the Faculty of Physics, Jagiellonian University, in close collaboration with URANOS scientists, have studied a two-dimensional electron gas (2DEG) formed on a tellurium-passivated InAs(110) surface. High-resolution ARPES measurements have been performed as a function of temperature and 2DEG sheet density, to study the many-body interactions within the 2DEG. The band shapes and their widths have been discussed in detail.

Electronic structure studies of Chiral Quantum Materials.

29.05.2023
Led by Professor Antonio Politano from the University of L’Aquila, Italy the team together with beamline scientists from URANOS beamline has identified and characterized a new chiral material, CdAs2, which exhibits a rare Kramers-Weyl fermion. Chirality, which refers to the asymmetry in the spatial arrangement of molecules, plays a crucial role in a wide range of scientific fields, including biochemistry and materials science. Chiral crystals exhibit well-defined handedness due to the breaking of inversion, mirror, or any other roto-inversion symmetries.
