Abstract
Abstract—The possibility of the local all-optical magnetization reversal in a thin ferrimagnetic rare-earth—transition metal film (DeFeCo) by linearly and circularly polarized 35 fs laser pulses is demonstrated experimentally. Conditions of the exposure to unit pulse and pulse sequence without an applied external magnetic field are used. The found peculiarities of switching in DyFeCo differ substantially from the results obtained previously for rare-earth—transition metal alloys. The minimum nominal fluence for the magnetization reversal is 3 mJ/cm2.
