The magnetic structure of the quasi-two-dimensional antiferromagnet NiPS3 has been determined by magnetometry and a variety of neutron diffraction techniques. The experiments show that the samples must be carefully handled, as gluing influences the magneto ...
We report a broadband H-1 NMR study of the spin dynamics of coated maghemite and goldmaghemite hybrid nanostructures with two different geometries, namely dimers and coreshells. All the samples have a superparamagnetic behavior, displaying a blocking tempe ...
The synthesis, structural characterization and magnetic properties of a 1D zig-zag coordination polymer based on a cation-cation [((UO2)-O-V)Mn-II] repeated unit are reported; it shows single chain magnet (SCM) behaviour with a high energy barrier of 122 K ...
The effects of external (hydrostatic) compression and internal (chemical) expansion on the skyrmion phase have been investigated in Cu2OSeO3 single crystal and Cu2OSe1-xTexO3 (0
We present a systematic study of the crystal-field interactions in the LiRF4 (R = Gd, Ho, Er, Tm, and Yb) family of rare-earth magnets. Using detailed inelastic neutron scattering measurements, we have been able to quantify the transition energies and wave ...
Sc2Ga2CuO7 (SGCO) crystallizes in a hexagonal structure (space group: P63/mmc), which can be seen as an alternating stacking of single and double triangular layers. Combining neutron, x-ray, and resonant x-ray diffraction, we establish that the single tria ...
Nearly seven decades of research on microwave excitations of magnetic materials have led to a wide range of applications in electronics(1-4). The recent discovery of topological spin solitons in chiral magnets, so-called skyrmions(5-9), promises high-frequ ...
Competing Jahn-Teller distortions combined with geometrical frustration give rise to a rich phase diagram as a function of x(Cu) and temperature in the spinel system Ni1-xCuxCr2O4. The Jahn-Teller distortion of the end members acts in opposite ways, with a ...
Insulating helimagnetic Cu2OSeO3 shows sizeable magnetoelectric effects in its skyrmion phase. Using magnetization measurements, magneto-current analysis and dielectric spectroscopy, we provide a thorough investigation of magnetoelectric coupling, polariza ...
