We report on a theoretical study of thermal magnetization switching induced by nanosecond electric current pulse using Lagrangian formalism based on the Landau–Lifshitz–Gilbert equation. The parameters for modeling are obtained from the measurements of the anomalous Hall resistance at different probe currents. We obtain the switching diagrams, analyze how the switching rate depends on the pulse parameters and the applied magnetic field, and find the optimal set of values such as orientation of the field, electric pulse duration, and energy consumption. We find that the magnetization switching is particularly efficient near the compensation point, where a decrease in the magnetization of the rare-earth sublattices by 10% or less can lead to reversal of net magnetization.

• Exhibited an excellent selective fluorescence response. • Distinct detections of Zn2+ and Al3+. • Show different emission wavelengths for Zn2+ and Al3+. Fluorescent probe NA was synthesized to investigate its fluorescence properties toward metal ions. Probe NA exhibited an excellent selective fluorescence response for the distinct detection of Zn2+ and Al3+ in CH 3 CN/H 2 O (7:3, v/v). The detection limits of probe NA for Zn2+ and Al3+ were 14.4 and 74.0 µM, respectively. The density functional theory results indicated that the upper form was suitable for the formation of the probe NA –Zn2+ or probe NA –Al3+ complex. [ABSTRACT FROM AUTHOR]
