Magnetostructural domain wall patterning in ferrimagnetic spinels

ORAL

Abstract


The ferrimagnetic spinels Mn3O4 and MnV2O4 are known for their anomalous magnetoresponsive behavior, including strong magnetoelastic and magnetodielectric coupings. Mechanically strained samples of these materials show a real-space separation of the volume into stripe-like regions of alternating magnetization on the nanometer lengthscale. I will show small angle neutron scattering data associating these features with known first order magnetic transitions in these materials, and their control via applied magnetic field. I will then draw a direct connection to bulk magnetic measurements, and demonstrate how these domains can lead to anomalous magnetization behaviors.
