Raman Effect During Formation of the Ordered L10-FePd Phase
591–601 (2024)

PACS numbers: 68.55.Nq, 75.30.Kz, 75.50.Vv, 75.60.Ej, 75.70.Ak, 78.30.Er, 81.30.Hd

Effect of the hydrogen heat treatment compared with vacuum annealing in the temperature range of 500–700 C on the formation of the ordered L10-FePd phase and variations in Raman spectra of the equiatomic FePd films are studied. The hydrogen atoms introduced into the nanoscale FePd films change the electronic structure and magnetic properties and states of the film. Ordering processes are accelerated under hydrogen treatments compared with vacuum annealing. By changing of parameters of the hydrogen annealing of the FePd film, it is possible to control the phase composition, ferromagnet -- paramagnet-variation in the magnetic states. The Raman spectroscopy allows investigate the dynamics of structural changes in the FePd films during the ordering and the ordered L10-FePd-phase formation

KEY WORDS: hydrogen, ordering, coercivity, Raman scattering spectroscopy, paramagnetism, hard-magnetic material, L10-FePd, magnetization
