The magnetic state of atomically thin semiconducting layered antiferromagnets such as CrI3 and CrCI3 can be probed by forming tunnel barriers and measuring their resistance as a function of magnetic field (H) and temperature (T). This is possible because t ...
An experimental study of long-range magnetic order formation mechanisms in a layered structure with a honeycomb arrangement of the magnetic atoms Na2Ni2TeO6 is conducted. For the first time, the strong spin correlations are directly observed above the Neel ...
Potassium chromium jarosite, KCr3(OH)(6)(SO4)(2) (Cr-jarosite), is considered a promising candidate to display spin liquid behavior due to the strong magnetic frustration imposed by the crystal structure. However, the ground state magnetic properties have ...
Temperature dependence of the antiferromagnetic resonance spectrum in a thulium orthoferrite (TmFeO3) poly-crystalline sample was studied by transmission spectroscopy in the frequency range of 0.1–0.75 THz and temperature range of 300–670 K, up to its Néel ...
Long-range magnetic ordering and short-range spin correlations in layered noncentrosymmetric orthogermanate Li2MnGeO4 were studied by means of polarized and unpolarized neutron scattering. The combined Rietveld refinement of synchrotron and neutron powder ...
Two isostructural double halide-bridged polymers, consisting of stacked Cu2L2X4 dimers, with L = benzamide (BA) and X = Cl- in CuClBA and X = Br- in CuBrBA, were synthesised. The experimental magnetic data of both compounds were recorded and it was found t ...
Using density-functional theory (DFT) band-structure calculations, we study the crystal structure, lattice dynamics, and magnetic interactions in the Shastry-Sutherland magnet SrCu2(BO3)(2) under pressure, concentrating on experimentally relevant pressures ...
CERN is the European Organization for Nuclear Research located in Geneva, Switzerland. Its main goal is to explore fundamental physics and it exists primarily to provide physicists the necessary tools for doing this, namely accelerators. These tools bring ...
The family of atomically thin magnets holds great promise for a number of prospective applications in magneto-optoelectronics, with CrI3 arguably being its most prototypical member. However, the formation of defects in this system remains unexplored to dat ...
Recent years have seen spectacular developments in the domain of nano-optics.
Alongside the well-known techniques of super-resolution microscopy progress
in nanofabrication has enabled important improvements in the fields
of optical imaging and spectros ...
