The imaginary parts of the ac susceptibility of in LDps. The data shows multiple frequency curves taken from 100 to 10 000 Hz. Solid and dashed lines alternate between the different frequency curves. The inset shows the Néel-Arrhenius plot from which the properties are extracted.

FIG. 3.

Initial magnetization curves from 2 to 30 K. The magnetic properties are extracted by fitting the model to these curves above 5 kOe. The model fits very well and the fits are shown with dashed lines.

The extracted susceptibility at different temperatures is shown. The 15 K peak is taken to be . The solid line is a guide to the eye.
