Título: | Creation of single chiral soliton states in monoaxial helimagnets |
Autor: | Osorio, Santiago; Laliena, Victor CSIC ORCID; Campo, Javier CSIC ORCID ; Bustingorry, Sebastian CSIC ORCID | Fecha de publicación: | 2021 | Editor: | American Institute of Physics | Citación: | Applied Physics Letters 119822): 222405 (2021) | Resumen: | In monoaxial helimagnets, the Dzyaloshinskii–Moriya interaction favors inhomogeneous distributions of the magnetization with chiral modulations of solitonic character. In addition to the helical magnetic state at zero field, a chiral soliton lattice can be stabilized when a magnetic field perpendicular to the chiral axis is applied. When the magnetic field is increased, the system undergoes a phase transition to the uniform state at a critical field Bc. Above Bc, a single chiral soliton comprises the lowest level excitation over the stable uniform state, surviving as a metastable configuration. How to retain a single chiral soliton metastable state has not been addressed yet. Using micromagnetic simulations, we analyze this possibility by injecting spin polarized currents and put forward a feasible protocol to obtain a state with a single chiral soliton from the chiral soliton lattice. Our proposal could be relevant in the experimental study of metastable solitons for technological applications. | Versión del editor: | https://doi.org/10.1063/5.0067682 | URI: | http://hdl.handle.net/10261/265584 | DOI: | https://doi.org/10.1063/5.0067682 | E-ISSN: | 1077-3118 |
