Topological textures and emergent altermagnetic signatures in ultrathin BiFeO3
George Fratian, Maya Ramesh, Xinyan Li +23
Magnetoelectric multiferroics, materials with intrinsically coupled electric polarization and magnetic order, promise ultralow-power switching, nonvolatile memory, and energy-effic…
Anisotropic magnon transport in an antiferromagnetic trilayer heterostructure: is BiFeO an altermagnet?
Sajid Husain, Maya Ramesh, Qian Song +18
Magnons provide a route to ultra-fast transport and non-destructive readout of spin-based information transfer. Here, we report magnon transport and its emergent anisotropic nature…
Low-energy domain wall racetracks with multiferroic topologies
Arundhati Ghosal, Alexander Qualls, Yousra Nahas +13
Conventional racetrack memories move information by pushing magnetic domain walls or other spin textures with spin-polarized currents, but the accompanying Joule heating inflates t…
Colossal enhancement of spin transmission through magnon confinement in an antiferromagnet
Sajid Husain, Maya Ramesh, Xinyan Li +21
Since Felix Bloch's introduction of the concept of spin waves in 1930, magnons (the quanta of spin waves) have been extensively studied in a range of materials for spintronics, par…
Poincaré sphere engineering of dynamical ferroelectric topological solitons
Lingyuan Gao, Yijie Shen, Sergei Prokhorenko +2
Geometric representation lays the basis for understanding and flexible tuning of topological transitions in many physical systems. An example is given by the Poincaré sphere (PS)…
Morphogenesis of Spin Cycloids in a Non-collinear Antiferromagnet
Shashank Kumar Ojha, Pratap Pal, Sergei Prokhorenko +11
Pattern formation in spin systems with continuous-rotational symmetry (CRS) provides a powerful platform to study emergent complex magnetic phases and topological defects in conden…
