Article Abstract
The B-site sublattice in the double perovskite oxides ABB'O (B: magnetic cation; B': nonmagnetic cation) causes spin frustration, but the relationship between the structure and spin frustration remains unclear although a number of compounds have been studied. The present study systematically investigated AMnB'O ( = 5/2) and found that the frustration factor, defined by = |θ|/ (θ: Weiss temperature; : Néel temperature), scales linearly with the tolerance factor , i.e., octahedral rotation. Unexpectedly, LaMnTaON (space group: 2/) synthesized under high pressure is more frustrated ( = 6) than oxides with similar values, despite the large octahedral rotation due to the small value of 0.914. Structural analysis suggests that the enhanced frustration can be attributed to the site preference of nitride anions at the equatorial positions, which reduces the variance of neighboring Mn-Mn distances. Our findings provide a new guide to control and improve spin frustration in double perovskites with multiple anions.

The BaGdRuO double perovskite oxide demonstrates intriguing behavior, arising from competing antiferromagnetic (AFM) and ferrimagnetic (FiM) phases. Under the GGA++SOC scheme, the system exhibits an AFM ground state with a very small energy difference of -11.39 meV compared to the FiM one.

Single-phase dysprosium orthoferrite (DyFeO: DFO) nanoparticles have been synthesized using the nanoagitator bead mill. Rietveld refinement of the experimental X-ray diffraction (XRD) pattern confirms the orthorhombic crystal symmetry ( space group) of the material. The surface morphology, grain size distribution, and color mapping were analyzed.

Chiral interactions within magnetic layers stabilize the formation of noncollinear spin textures, which can be leveraged to design devices with tailored magnetization dynamics. Here, we introduce chiral spin frustration in which energetically degenerate magnetic states frustrate the Dzyaloshinskii-Moriya interaction. We demonstrate magnon-driven switching of the chirally frustrated spin states in Bi-substituted yttrium iron garnet thin films.

Unlike conventional magnetic states, which lack degeneracy, the spiral spin liquid (SSL) fluctuates among degenerate spiral configurations, with ground-state wave vectors forming a continuous contour or surface in reciprocal space. At low temperatures, the field-induced crossover from the polarized ferromagnetic state to the SSL results in a large entropy increase and decalescence, indicating its potential for magnetic cooling. However, magnetic cooling using a SSL has yet to be reported.

V-V dimerization in ilmenite-type vanadium oxides is an intriguing phenomenon that induces structural and metal-to-insulator transitions. Herein, we report the high-pressure synthesis, crystal structure, and electronic and magnetic states of high-entropy ilmenite-type (MgMnCoNiCu)VO. Although all the parent ilmenite-type compounds exhibit triclinic (1̅) symmetry at room temperature, this compound crystallizes in a rhombohedral (3̅) structure, indicating the absence of long-range V-V dimer ordering.
