Detection of picosecond magnetization dynamics of 50 nm magnetic dots down to the single dot regime
Bivas Rana, Dheeraj Kumar, Saswati Barman +4
We report an all-optical time-domain detection of picosecond magnetization dynamics of arrays of 50 nm Ni80Fe20 (permalloy) dots down to the single nanodot regime. In the single na…

All-Optical Excitation and Detection of Picosecond Dynamics of Ordered Arrays of Nanomagnets with Varying Areal Density
Bivas Rana, Semanti Pal, Saswati Barman +3
We have demonstrated optical excitation and detection of collective precessional dynamics in arrays of coupled Ni80Fe20 (permalloy) nanoelements with systematically varying areal d…
