Tuning the dynamics of magnetic droplet solitons using dipolar interactions

Autor: Yazdi, H. F., Ghasemi, G., Mohseni, Majid, Mohseni, Morteza

Publikováno v: Phys. Rev. B 103, 024441 (2021)

Magnetic droplets are dissipative magnetodynamical solitons that can form under current driven nanocontacts in magnetic layers with large perpendicular magnetic anisotropy. Here, we extend the original droplet theory by studying the impact of the dip

Controlling Magnetization of Gr/Ni Composite for Application in High Performance Magnetic Sensors

Autor: Hajiali, M. R., Jamilpanah, L., Sheykhifard, Z., Mokhtarzadeh, M., Yazdi, H. F., Tork, B., Gharehbagh, J. Shoa e, Azizi, B., Roozmeh, S. E., Jafari, G. R., Mohseni, Majid

Graphene (Gr), a well-known 2D material, has been under intensive investigation in the last decade due to its high potential applications in industry and advanced technological elements. The Gr, while composed with magnetic materials, has opened new

Chiral excitations of magnetic droplet solitons driven by their own inertia

Autor: Mohseni, M., Rodrigues, D. R., Saghafi, M., Chung, S., Ahlberg, M., Yazdi, H. F., Wang, Q., Banouazizi, S. A. H., Pirro, P., Åkerman, J.

Publikováno v: Phys. Rev. B 101, 020417 (2020)

The inertial effects of magnetic solitons play a crucial role in their dynamics and stability. Yet governing their inertial effects is a challenge for their use in real devices. Here, we show how to control the inertial effects of magnetic droplet so

Magnetic Droplet Soliton Nucleation in Oblique Fields

Autor: Mohseni, Morteza, Hamdi, M., Yazdi, H. F., Banuazizi, S. A. H., Chung, S., Sani, S. R., Åkerman, Johan, Mohseni, Majid

We study the auto-oscillating magnetodynamics in orthogonal spin torque nano-oscillators (STNOs) as a function of the out-of-plane (OOP) magnetic field angle. In perpendicular fields and at OOP field angles down to approximately 50 degrees we observe

Current induced multi-mode propagating spin waves in a spin transfer torque nano-contact with strong perpendicular magnetic anisotropy

Autor: Mohseni, S. Morteza, Yazdi, H. F., Hamdi, M., Bracher, T., Mohseni, S. Majid

Current induced spin wave excitations in spin transfer torque nano-contacts are known as a promising way to generate exchange-dominated spin waves at the nano-scale. It has been shown that when these systems are magnetized in the film plane, broken s
