Rare-earth-free ferrimagnetic Mn4N sub-20 nm thin films as potential high-temperature spintronic material

Autor: W. Zhou, C. T. Ma, T. Q. Hartnett, P. V. Balachandran, S. J. Poon

Publikováno v: AIP Advances, Vol 11, Iss 1, Pp 015334-015334-6 (2021)

Ferrimagnetic alloy thin films that exhibit perpendicular (out-of-plane) magnetic anisotropy (PMA) with low saturation magnetization, such as GdCo and Mn4N, were predicted to be favorable for hosting small Néel skyrmions for room temperature applica

Three-dimensional imaging of vortex structure in a ferroelectric nanoparticle driven by an electric field

Autor: D. Karpov, Z. Liu, T. dos Santos Rolo, R. Harder, P. V. Balachandran, D. Xue, T. Lookman, E. Fohtung

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-8 (2017)

Imaging of topological states of matter such as vortex configurations has generally been limited to 2D surface effects. Here Karpov et al. study the volumetric structure and dynamics of a vortex core mediated by electric-field induced structural phas

Publikováno v: APL Materials, Vol 2, Iss 7, Pp 076110-076110-9 (2014)

We show that the NiO6 crystal field energies can be tailored indirectly via heterovalent A cation ordering in layered (La,A)NiO4 Ruddlesden–Popper (RP) oxides, where A = Sr, Ca, or Ba, using density functional calculations. We leverage as a driving
