“…In both materials, the lowest temperature phases have been associated with large magnetoelastic and magnetodielectric response functions 20,21,24,24,34,35 and stripe-like magnetic domains in our previous study 25 . Our current SANS data build upon our initial MFM results and reveal the extension of low-temperature stripe-like domains to the bulk of each material.…”

“…Prime examples are found in the literature on ferrimagnetic spinel oxides. These materials are notable for strong spin-lattice coupling and the prevalence of low-temperature magnetostructural transitions 18 into states often characterized by giant magnetoelastic and magnetodielectric response functions [19][20][21][22][23][24] . Recent studies by some of us using magnetic force microscopy (MFM) 25 and oth-ers using transmission electron microscopy (TEM) 26,27 have revealed the existence of stripe-like magnetization domains in the same temperature region.…”

The manipulation of mesoscale domain wall phenomena has emerged as a powerful strategy for designing ferroelectric responses in functional devices, but its full potential has not yet been realized in the field of magnetism. We show that mechanically strained samples of Mn3O4 and MnV2O4 exhibit a stripe-like patterning of the bulk magnetization below known magnetostructural transitions, similar to the structural domains reported in ferroelectric materials. Building off our previous magnetic force microscopy data, we use small angle neutron scattering to show that these patterns extend to the bulk, and demonstrate an ability to manipulate the domain walls via applied magnetic field and mechanical stress. We then connect these domains back to the anomalously large magnetoelastic and magnetodielectric response functions reported in these materials, directly correlating local and macroscopic measurements on the same crystals.

The manipulation of mesoscale domain wall phenomena has emerged as a powerful strategy for designing ferroelectric responses in functional devices, but its full potential is not yet realized in the field of magnetism. This work shows a direct connection between magnetic response functions in mechanically strained samples of Mn 3 O 4 and MnV 2 O 4 and stripe-like patternings of the bulk magnetization which appear below known magnetostructural transitions. Building off previous magnetic force microscopy data, a small-angle neutron scattering is used to show that these patterns represent distinctive magnetic phenomena which extend throughout the bulk of two separate materials, and further are controllable via applied magnetic field and mechanical stress. These results are unambiguously connected to the anomalously large magnetoelastic and magnetodielectric response functions reported for these materials, by performing susceptibility measurements on the same crystals and directly correlating local and macroscopic data.

By a combination of magnetization M(T), M(H) and strain ΔL/L700K, ΔL/L0Oe, the positive magnetostrictions up to ∼5000 ppm originating from the rearrangement of tetragonal domains were observed in spinel Mn0.85Mg0.15V2O4, which exhibits two successive magnetic transitions at TC ∼ 42 K and T* ∼ 28 K. An anomalous magnetic hysteresis loop under a high field occurs below T*, caused by the rearrangement of tetragonal domains. We found that the Mg-doping at the Mn site can effectively promote the positive magnetostriction in Mn1-xMgxV2O4 systems. Moreover, the remnant strain can be significantly lowered by Mg-doping due to the enhancement of magnetic anisotropy. These results provide a possible approach for further optimizing the performance of magnetic shape-memory materials.
