Correlated regimes with slow dynamics in complex oxide LiMn2TeO6
https://doi.org/10.26907/mrsej-25302
Abstract
Mixed-valence manganese complex oxide LiMn2TeO6 has dimeric, chain and planar structure motifs. Three Mn positions form an antiferromagnetic framework, and the fourth one ferromagnetically couples with it. The studies by nuclear magnetic resonance (NMR), AC and DC magnetization, specific heat methods show a non-trivial scenario of spin system transformation as temperature decrease. A change in correlation regimes with slow dynamics in high magnetic fields is found, as well as an unusual magnetic static phase at T < 6K and B < 5T. All obtained results are summarized on the magnetic phase diagram.
