Recent investigations have advanced the understanding of how structure-property relationships in ferromagnetic metal alloys affect the magnetization dynamics on nanosecond time-scales. A similar understanding for magnetization dynamics on femtoto pico-second time-scales does not yet exist. To address this, we perform time-resolved magneto optic Kerr effect (TRMOKE) measurements of magnetization dynamics in Co-Fe alloys on femtoto nano-second regimes. We show that Co-Fe compositions that exhibit… Expand

Role of initial magnetic disorder: A time-dependent ab initio study of ultrafast demagnetization mechanisms
A fast, real-time time-dependent density functional theory (rt-TDDFT) algorithm together with the phenomenological atomic Landau-Lifshitz-Gilbert model to investigate laser-induced ultrafast demagnetization of ferromagnetic systems finds that the angular momentum flow from light to the system is not essential and the spin Zeeman effect is negligible.

Probing the timescale of the exchange interaction in a ferromagnetic alloy
This work uses extreme ultraviolet pulses from high-harmonic generation as an element-specific probe of ultrafast, optically driven, demagnetization in a ferromagnetic Fe-Ni alloy (permalloy), and shows that for times shorter than the characteristic timescale for exchange coupling, the magnetization of Fe quenches more strongly than that of Ni.

Critical behavior within 20 fs drives the out-of-equilibrium laser-induced magnetic phase transition in nickel
High-harmonic spectroscopies reveal that fast energy transfer within 20 fs triggers ultrafast magnetic phase transition in Ni and discover a new time scale in the process of ultrafast demagnetization, where the transient electron temperature alone dictates the magnetic response. Expand
Explaining the paradoxical diversity of ultrafast laser-induced demagnetization.
It is shown that a model based on electron-phonon-mediated spin-flip scattering explains both timescales on equal footing and concludes that the ultrafast magnetization dynamics can be well described disregarding highly excited electronic states, merely considering the thermalized electron system.

Unifying ultrafast magnetization dynamics.
It is found that tau(M) can be directly related to the so-called Gilbert damping factor sigma that describes damping of GHz precessional motion of the magnetization vector. Expand
Band structure evolution during the ultrafast ferromagnetic-paramagnetic phase transition in cobalt
It is found that the ferromagnetic-paramagnetic phase transition cannot be explained by a loss of the exchange splitting of the spin-polarized bands but instead shows rapid band mirroring after the excitation, which is a clear signature of extremely efficient ultrafast magnon generation. Expand
Optimal electron, phonon, and magnetic characteristics for low energy thermally induced magnetization switching
Using large-scale computer simulations, we thoroughly study the minimum energy required to thermally induced magnetization switching (TIMS) after the application of a femtosecond heat pulse in… Expand
Magnetic properties in ultrathin 3d transition-metal binary alloys. II. Experimental verification of quantitative theories of damping and spin pumping
A systematic experimental study of Gilbert damping is performed via ferromagnetic resonance for the disordered crystalline binary 3d transition-metal alloys Ni-Co, Ni-Fe, and Co-Fe over the full… Expand
Electron-magnon scattering in magnetic heterostructures far out of equilibrium
We present a theory of out-of-equilibrium ultrafast spin dynamics in magnetic heterostructures based on the s-d model of ferromagnetism. Both in the bulk and across interfaces, the exchange processes… Expand
