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

Structural phase diagram and magnetic properties of Sc-substituted rare earth ferrites R1−xScxFeO3 (R = Lu, Yb, Er, and Ho)
Substituting rare earth with Sc in RFeO3 results in rich structural phases including orthorhombic, hexagonal, bixbyite, and garnet, as reported in this work. See more details: J. Appl. Phys. 125, 244101 (2019).
Noncollinear spin structure in Fe3+xCo3−xTi2 (x = 0, 2, 3) from neutron diffraction
Neutron powder diffraction has been used to investigate the spin structure of the hard-magnetic alloy hexagonal Fe3+xCo3−xTi2 (x = 0, 2, 3). Projections of the magnetic moment onto both the crystalline c axis and the basal plane were observed. The corresponding misalignment angle exhibits a nonlinear decrease with x, which we explain as a micromagnetic effect caused by Fe-Co site disorder. See more details: Phys. Rev. Mat. 3, 064403 (2019).
