Low relaxation rate in a low-Z alloy of iron

C. Scheck, L. Cheng, I. Barsukov +2

The longest relaxation time and sharpest frequency content in ferromagnetic precession is determined by the intrinsic (Gilbert) relaxation rate \emph{}. For many years, pure iro…

Time-domain measurement of driven ferromagnetic resonance

Y. Guan, W. E. Bailey, E. Vescovo +2

We present a time-resolved measurement of magnetization dynamics during ferromagnetic resonance (FMR) in a single layer of Ni81Fe19. Small-angle (<1 deg.) precession of elemental N…

Dual-frequency ferromagnetic resonance

Yongfeng Guan, William E. Bailey

We describe a new experimental technique to investigate coupling effects between different layers or modes in ferromagnetic resonance (FMR). Dual FMR frequencies are excited (2-8 G…

Low Ghz loss in sputtered epitaxial Fe

C. Scheck, L. Cheng, W. E. Bailey

We show that sputtered, pure epitaxial iron films can have high-frequency loss as low as, or lower than, any known metallic ferromagnetic heterostructure. Minimum 34 Ghz ferromagne…

Precessional dynamics of elemental moments in a ferromagnetic alloy

W. E. Bailey, L. Cheng, D. Keavney +3

We demonstrate an element-specific measurement of magnetization precession in a metallic ferromagnetic alloy, separating Ni and Fe moment motion in Ni81Fe19. Pump-probe X-ray magne…

XMCD characterization of rare-earth dopants in NiFe(50nm): microscopic basis of engineered damping

W. E. Bailey, L. Cheng, H. Song

We present direct evidence for the contribution of local orbital moments to the damping of magnetization precession in magnetic thin films. Using x-ray magnetic circular dichroism…
