Magnetic texture modulated superconductivity in superconductor/ferromagnet shells of semiconductor nanowires

Nabhanila Nandi, Juan Carlos Estrada Saldaña, Alexandros Vekris +11

In a one-dimensional ferromagnet-superconductor nanowire, magnetism can suppress superconductivity except where the Zeeman field is suppressed, for example domain wall superconduct…

Magnetic topological textures in nonorientable surfaces

Carlos Saji, Mario A. Castro, Vagson L. Carvalho-Santos +3

Topological magnetic textures confined to two-dimensional (2D) non-orientable manifolds exhibit behaviors absent in planar systems. We investigate bimerons on Möbius surfaces and…

Antiferron Modes in Ferroelectric Materials

David Galvez-Poblete, Mario A. Castro, Roberto E. Troncoso +3

We introduce the concept of antiferron modes in ferroelectric materials as dynamically stabilized collective excitations over inverted polarization states that decrease the system…

Elastic Dislocation-based Skyrmion Traps: Fundamentals and Applications

Martín Latorre, Joaquín Barra, Juan Pablo Vera +4

Topologically secure spin configurations, such as skyrmions and bimerons, offer a compelling alternative to conventional magnetic domains, potentially enabling high-density, low-po…

Quantized Piezospintronic Effect in Moiré Systems

Mario Castro, Benjamín Mancilla, Fabian Wolff +1

This paper presents a novel approach for generating and controlling spin currents in an antiferromagnetic twisted honeycomb bilayer in response to an elastic deformation. Utilizing…

Magnetic Worms: Oscillatory Bimeron Pairing And Collective Transport In Patterned Stripes

Jose Toledo-Marin, Mario Castro, David Galvez-Poblete +4

Magnetic bimerons in a domain wall provide a practical route for current driven transport in patterned magnetic stripes. However, coupling between bimerons and pinning by defects c…
