We, as a group, learn, explore, and make discoveries together.

Magnetism and epitaxy of h-RFeO3/Fe3O4
We have found that h-RFeO3(001)/Fe3O4(111) may form well-defined interface due to good match of lattice constant. It is also interesting that the magnetic easy axis of the two layers are perpendicular to each other: easy axis of Fe3O4 layer in (111) plane; easy axis of h-RFeO3 layer along  direction.

Strain effect in h-LuFeO3 measured using restrained thermal expansion
The effect of biaxial strain in hexagonal ferrites has been challenging to tackle due to the experimental difficulties. Employing the restrained thermal expansion method, we successfully measured the strain effect. The results show that the compressive strain enhances the K3 lattice distortion. Our first principle calculation indicate that the compressive strain also enhances the electric polarization bu reduces the magnetic polarization. See more details: Phys. Rev. B. 95, 094110 (2017) .
Anti-site mixing and magnetic properties of Fe3Co3Nb2
Fe3Co3Nb is a newly discovered alloy that potentially exhibit high magnetic anisotropy and high saturation magnetization, which is appealing for application as a permanent magnet. Using neutron powder diffraction, we have found strong Co/Fe anti-site mixing, which explains the difference between the measured and predicted magnetic anisotropy and hints a route toward how to enhance it.
