Solvothermal Synthesis of SrFe12O19 Hexaferrites: Without Calcinations

Journal 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.

A Frustrated Antipolar Phase Analogous to Classical Spin Liquids. [PDF]

Adv Mater
EuAl12O19 crystals realize an electric analogue to one of the famous models of frustrated magnetism: the Ising triangular lattice antiferromagnet. Electric dipoles on a triangular lattice preferentially align antiparallel to their neighbors yet fail to form any long‐range order, even at the lowest temperatures.
