As magnetic materials approach their Curie temperature (Tc), they exhibit critical behavior, including divergent susceptibilities, long-range correlations, and spin dynamics across a wide frequency range. However, observing these effects remained challenging thus far, due to the scale and magnitude of such effects, well beyond traditional measurement techniques.
In new research led by Benjamin Lawrie at Oak Ridge National Lab, scientists used Qnami ProteusQ to investigate the phase transition of Sr2FeReO6, a high-Tc ferromagnetic oxide. From a careful analysis of nanoscale magnetic textures and spin dynamics the authors conclude that the…
