The existence of the V-ion orbital moment is an open issue of the nature of magnetism in the van der Waals ferromagnet VI. The huge magnetocrystalline anisotropy in conjunction with the significantly reduced ordered magnetic moment compared to the spin-only value provides strong but indirect evidence of a large V orbital moment. We used the unique capability of X-ray magnetic circular dichroism to determine the orbital component of the total magnetic moment and provide a direct proof of an exceptionally sizable orbital moment of the V ion in VI. Our ligand field multiplet simulations of the XMCD spectra in synergy with the results of DFT calculations agree with the existence of two V sites with different orbital occupations and OM magnitudes in the ground state.

The detailed anisotropic dispersion of the low-temperature, low-energy magnetic excitations of the candidate spin-triplet superconductor UTe is revealed using inelastic neutron scattering. The magnetic excitations emerge from the Brillouin zone boundary at the high symmetry and points and disperse along the crystallographic -axis. In applied magnetic fields to at least = 11 T along the , the magnetism is found to be field-independent in the ( 0) plane.

Despite their frequent co-occurrence in real life, the commonality and distinction between social interaction perception and ToM at behavioral and neural levels remain unclear. Here, participants ( = 231) provided moment-by-moment ratings of four text and four audio narratives on social interactions and ToM engagement.

An exotic quantum mechanical ground state, i.e. the nonmagnetic= 0 state, has been predicted for higher transition metal tsystems, due to the influence of strong spin-orbit coupling (SOC) or in other words, due to unquenched orbital moment contribution.

We systematically investigate the magnetization and thermodynamic responses associated with antiferromagnetic (AFM) transitions in single crystals of the magnetic semiconductor Eu3InAs3. The linear thermal expansion measurements around the AFM transition temperatures, TN1 and TN2, indicate an expansion along the a axis and contraction along the b and c axes. The calculated ∆V/V(T) shows a continuous change at TN, indicating a second-order magnetic phase transition.

Article Synopsis
- The study focuses on Kcoronene, a potassium-intercalated polycyclic aromatic hydrocarbon, detailing its synthesis, structure, and magnetic properties while outlining a computational method to identify suitable PAHs for metal intercalation.
- Coronene was selected based on a screening of its electronic structure and available void space, demonstrating stability when intercalated with three potassium ions per coronene molecule.
- Despite structural changes and disorder caused by potassium intercalation, Kcoronene did not exhibit superconductivity, which contrasts with earlier findings and may be linked to the extensive structural disruption observed.
