Ferromagnetic resonance study of the Half-Heusler alloy NiMnSb

The research explores the significance of spin torque, discovered in 1996, in advancing information storage and communication technologies. It highlights the potential of using current to switch magnetic configurations, enabling the development of high-frequency spin torque oscillators. A key focus is on ferromagnets with low damping, as lower damping reduces the critical current required for switching or magnetization precession. NiMnSb emerges as a promising candidate due to its low magnetic damping and high spin-polarization, making it ideal for future spintronic devices.
