Optically-induced frequency up-conversion of the ferromagnetic resonance in an ultrathin garnet
Lucile Soumah, Davide Bossini, Abdelmadjid Anane +1
We perform ultrafast pump-probe measurements on a nanometer-thick crystalline Bi-doped yttrium iron garnet film with perpendicular magnetic anisotropy. Tuning the photon energy of…
Nanoscale transient magnetization gratings excited and probed by femtosecond extreme ultraviolet pulses
D. Ksenzov, A. A. Maznev, V. Unni +15
We utilize coherent femtosecond extreme ultraviolet (EUV) pulses derived from a free electron laser (FEL) to generate transient periodic magnetization patterns with periods as shor…
Anisotropic Ultrafast Spin Dynamics in Epitaxial Cobalt
Vivek Unikandanunni, Rajasekhar Medapalli, Eric E. Fullerton +3
We investigate the ultrafast spin dynamics in an epitaxial hcp(1100) cobalt thin film. By performing pump-probe magneto-optical measurements with the magnetization along either the…
Analysis in k-space of Magnetization Dynamics Driven by Strong Terahertz Fields
Valentino Scalera, Matthias Hudl, Kumar Neeraj +4
Demagnetization in a thin film due to a terahertz pulse of magnetic field is investigated. Linearized LLG equation in the Fourier space to describe the magnetization dynamics is de…
NTMpy: An open source package for solving coupled parabolic differential equations in the framework of the three-temperature model
Lukas Alber, Valentino Scalera, Vivek Unikandanunni +2
The NTMpy code package allows for simulating the one-dimensional thermal response of multilayer samples after optical excitation, as in a typical pump-probe experiment. Several Pyt…
