FIG. 1.

Field dependence of the magnetization of Nd2/3Ca1/3MnO3 at 10 K after ZFC and FC in H cool = 800 Oe.

Real (χ′) and imaginary (χ′′) components of the ac susceptibility of Nd2/3Ca1/3MnO3 measured at different frequencies.

FIG. 3.

Argand diagrams of Nd2/3Ca1/3MnO3 for different temperatures below (a) and above (b) the freezing temperature Tg ∼ 60 K. The curves are fits according to Eq. (1).

Image of FIG. 4.
FIG. 4.

The time dependence of ZFC magnetization for Nd2/3Ca1/3MnO3 at 10 (a) and 79 (b) K. The magnetization data were collected immediately after applying the magnetic field μ0H = 10 mT. The solid curve is the best fit of the magnetic relaxation by Eq. (2). The dashed curve is a guide for eye only. The peak on the curve at T = 79 K is related to the competition between two different relaxation mechanisms.
