Abstract

In this paper, the rare earth cobaltite Nd1-xSrxCoO3 (0.1<=x<=0.5) samples were prepared using conventional solid
state reaction method. Dc magnetization, ac susceptibility, magnetic relaxation of polycrystalline Nd1-xSrxCoO3
is investigated in detail. The presence of the typical features of spin/cluster glass state in x<+0.2 samples was well
revealed by ac susceptibility. Therefore, our study confirms that the phase separation in Nd1-xSrxCoO3 originates
from both the ferromagnetic clusters interaction and the spin glasslike phase at low temperature.
