Spin-Wave Resonance in Metals

Studies of ferromagnetic resonance line width during electrochemical deposition of Co films on Au(111)

“…Due to the setup geometry and the skin effect of the microwave in the X-band [12], a larger thickness was not suitable for the in situ FMR investigations. The samples which measured ex situ with conventional angle-dependent FMR showed an enlarged magnetization (2.2 Â 10 6 A/m) and a significant reduction in the magneto-crystalline anisotropy (K 1 =M ¼ 4 mT) as compared to Co bulk values.…”

Micromagnetic Approach to Exchange Bias

“…g is the Landé g-factor and µ B is the Bohr magneton. The gvalues of pure metals g = 2.09 (Fe), g = 2.18 (Co), and g = 2.21 (Ni) deviate from the spin-only value by some amount [7,13]. The same concerns the Heusler alloys (g = 2.05−2.0) [14,15] and magnetite (g = 2.12).…”

TETRAGONAL HEUSLER-LIKE Mn–Ga ALLOYS BASED PERPENDICULAR MAGNETIC TUNNEL JUNCTIONS

“…50 Barman et al had rst applied this method to observe magnetization precessional dynamics for the Co/Pt multilayer with a large PMA, and they reported very large damping constant of about 0.1, 51 which was 10-100 times larger than those for the conventional Fe, Co, Ni and their alloys ( ¼ 0:002-0.02). 52 Mizukami et al have pointed out the common physical origin behind Gilbert damping and magnetic anisotropy, namely the spin-orbit interaction, and they reported large damping more than 0.1 in Pt/Co/Pt trilayers wih PMA, and discussed the origin of large damping and correlation between PMA and the enhanced damping in addition to spin pumping e®ect. 47,53 In Fig.…”
