ASb3Mn9O19 (A = K or Rb): New Mn‐Based 2D Magnetoplumbites with Geometric and Magnetic Frustration

open access: yesAdvanced Materials, Volume 37, Issue 10, March 12, 2025.
The first Mn‐based magnetoplumbites, ASb3Mn9O19 (A = K or Rb), are discovered, synthesized, and characterized. According to magnetic properties measurements, neutron diffraction, and reverse Monte Carlo refinement, short‐range magnetic correlations are observed in the new materials.

Solvothermal Synthesis of SrFe12O19 Hexaferrites: Without Calcinations

open access: yesJournal of Superconductivity and Novel Magnetism, 2014
In this study, the effect of temperature on the hydrothermal synthesis of single-phase SrFe12O19 hexaferrite (SrM) was investigated. For this synthesis, annealing or calcination process was applied. The Fe/Ba molar ratio was taken as 8:1. In this study, single-phase SrM NPs were synthesized via hydrothermal method.
