Abstract

This repository contains data along with associated output from instrumentation supporting all results reported in Huang, D.; Zhang, D.; Kim, Y; Wang, J.P.; and Wang X. Magnetization dynamics in synthetic antiferromagnets with perpendicular magnetic anisotropy. Phys. Rev. B., 2023, 107, 214438. The magnetization dynamics of the perpendicular synthetic antiferromagnets (p-SAFs) sample is detected by time-resolved magneto-optical Kerr effect (TR-MOKE), which is ultrafast-laser-based metrology utilizing a pump-probe configuration. In TR-MOKE, pump laser pulses interact with the sample, initiating magnetization dynamics in magnetic layers via inducing ultrafast thermal demagnetization. The laser-induced heating brings a rapid decrease to the magnetic anisotropy fields and interlayer exchange coupling (IEC), which changes equilibrium direction of magnetization in each layer and initiates the precession. The magnetization dynamics due to pump excitation is detected by a probe beam through MOKE. In our setup, the incident probe beam is normal to the sample surface (polar MOKE); therefore, the Kerr rotation angle (θ_K) of the reflected probe beam is proportional to the z component of the magnetization.

Description

The repository contains six .csv files for all raw experimental data for plots, following the order of figure numbers. Data in ‘TR-MOKE signals’ .csv are used to extract frequency, amplitude, phase, and damping shown in Figs. 2,4,5.
