Image of FIG. 1.
FIG. 1.

Reproduced from Fig. 1 of Nabialek et al. Ref. 12. Their measurements of the transverse magnetostriction loop of a polycrystalline sample. The hysteresis loops were measured after cooling the sample in zero external magnetic field to 10, 15, 20, and .

FIG. 2.

Reproduced from Fig. 2 of Nabialek et al. Ref. 12. Scaling of the magnetostriction hysteresis loops of Fig. 1. The magnetostriction data (shown in Fig. 1) were normalized to their maximum values at each temperature, as shown in the inset (a). The external magnetic field at each temperature was normalized to the value of the irreversibility field as shown in the inset (b).

FIG. 3.

A family of normalized magnetostriction curves vs for comparison with Fig. 1. The curves were calculated using Eqs. (2) and (4). Here , , and .

FIG. 4.

The family of calculated curves of Fig. 3, scaled using the procedure described in the caption to Fig. 2, for comparison with the scaled measured curves displayed in Fig. 2.

Image of FIG. 5.
FIG. 5.

The outermost theoretical magnetostriction curve of Fig. 3 (shaded). The continuous dark curve was calculated with the same input as the former, except that here , hence the normal state component of Eq. (2) is absent. We note that the latter curve does not traverse into the dilatation region as ascends to its maximum magnitude.

Image of FIG. 6.
FIG. 6.

Family of magnetostriction curves measured by de Visser et al. Ref. 23 on a single crystal sample of (their Fig. 4).

Image of FIG. 7.
FIG. 7.

A family of normalized magnetostriction curves vs for comparison with Fig. 6. The curves were calculated using Eqs. (2) and (5). Here , , , and , 4.5, and 6 for the top, middle, and bottom curves respectively.

Image of FIG. 8.
FIG. 8.

The “normal state component” vs , introduced in the calculations of the magnetostriction curves displayed in Fig. 7 and calculated using Eq. (5).
