Time-resolved spin dynamics in dot arrays. a Sketch of time-resolved Kerr rotation measurement of spin component Sz. b Recorded Sz(t) at a fixed external magnetic field of a 600 nm dot array. c Extracted phase of the oscillation Sz(t) at positive zero-delay (\({{t}}_0^ +\)) and at negative zero-delay (\({{t}}_0^ -\)) of a 600 nm dot array. d Recorded Sz(t) as a function of external magnetic field B for 600 nm dot size array. The values of Sz(t) are color coded and normalized to ±1
