Photo-induced Antiferromagnetic-ferromagnetic Transition and Electronic Structure Modulation in GdBaCo${}_2$O${}_{5.5}$ Thin Film

Yujun Zhang, Tsukasa Katayama, Akira Chikamatsu +9

We investigate both the ferromagnetic (FM) and antiferromagnetic (AFM) ultrafast dynamics of a strongly correlated oxide system, GdBaCo${}_2$O${}_{5.5}$ thin film, by time-resolved x-r…
