Nonlinear magnetic response from the Ru0.9Sr2YCu2.1O7.9 magnetosuperconductor and its resultant phase separation
We investigated the third harmonic nonlinear susceptibility of the Ru0.9Sr2YCu2.1O7.9 magnetosuperconductor and found the presence of two well separated negative peaks. The peak at TM = 140 K is connected to the previously well known main magnetic ordering of the Ru sublattice, and the peak at around 180 K is probably associated with the formation of superparamagnetic particles above TM. The negative signals for both peaks will be discussed in terms of ensuing magnetic orderings of Ru spins at these temperatures. Further, these results will be compared with a recent study of nonlinear susceptibility on RuSr2GdCu2O8.
