FIG. 1.

Sample holder construction nesting the sample inside. The rule at the right side is used for positioning of sample at 4 cm.

Image of FIG. 2.
FIG. 2.

Three samples installed in the holder. (a) Solid piece of nickel. (b) Dy2O3 powder shaped to a 7 mm × 2.5 mm cylinder. (c) Nickel thin film (about 100 nm) sputter deposited on a 1.7 × 3 mm2 quartz surface, mounted perpendicular to the measurement field.

FIG. 3.

Magnetization vs. temperature of the nickel bulk sample measured at H = 2 kOe. Inset: magnetization vs. magnetic field at 500 K and 800 K.

Image of FIG. 4.
FIG. 4.

Reciprocal ac susceptibility of the nickel bulk sample showing evidence of the ferromagnetic to paramagnetic transition at T c = 631.42 ± 0.4 K. The solid line represents the extrapolation of the Curie-Weiss law characteristic of the paramagnetic phase.

Image of FIG. 5.
FIG. 5.

Alternating current susceptibility phase of the Dy2O3 measured from 300 to 400 K without the oven sample space. The holder does not induce any phase shift relative to the ac drive field applied.

Image of FIG. 6.
FIG. 6.

Magnetic moment at 300 K of the nickel thin film and empty sample holder. Inset: magnetic moment vs temperature at 2 kOe of the nickel thin film showing the ferromagnetic to paramagnetic transition at Tc ∼ 630 K.
