The effect of grain boundaries on the domain wall dynamics in Pr${}_{1-x}$Ag${}_x$MnO${}_3$ manganites

Hossein Ahmadvand, Hadi Salamati, Parviz Kameli

We performed detailed ac susceptibility measurements on Pr${}_{1-x}$Ag${}_x$MnO${}_3$ ($x$=0.15, 0.20) manganites and observed unusual and interesting features, which are associated with…
