Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201405244-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Mn²⁺₂Fe²⁺W⁶⁺O₆, a new polar magnetic phase</bold>, adopts the corundum‐derived Ni₃TeO₆‐type structure with large spontaneous polarization (<italic>P</italic>_S) of 67.8 μC cm⁻², complex antiferromagnetic order below ≈75 K, and field‐induced first‐order transition to a ferrimagnetic phase below ≈30 K. First‐principles calculations predict a ferrimagnetic (<italic>udu</italic>) ground state, optimal switching path along the <italic>c</italic>‐axis, and transition to a lower energy <italic>udu</italic>–<italic>udd</italic> magnetic double cell. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjf4gf3sk" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
