Exploring the Effects of Pressure on the Magnetic Phases in the Co doped MnWO₄ system

Cobalt doped MnWO₄ is a type 2 multiferroic compound and is also known to have one of the most complex and rich phase diagrams to date. Multiferroic materials are well understood to be sensitive to small perturbations which may be introduced through chemical substitution, magnetic and electric fields, or external pressure which can result in new states. Now these new states can have different magnetic orders and/or ferroelectric properties, which can lead to a wonderfully complex phase diagram to explore. Previously completed neutron measurements conducted at ambient and high pressure have resolved the complex magnetic phase diagram.
Therefore, to gain further insight into this system systematic high pressure dielectric measurements were conducted across the phase diagram at key cobalt dopings. These measurements coupled with previously discussed polarization measurements give the finally pieces to complete the pressure dependent phase diagrams across this rich phase diagram.
