“…For magnetic measurements, the Fe and Ni samples were cut into picture frames with [100] and [010] frame axes and rings, respectively [21,22,23]. To obtain a sample with low defect densities, a ring sample of as-grown Ni single crystal used in previous measurements [21,22] was annealed at T = 1373 K for a day.…”

Magnetic hysteresis loops reflect the variety of magnetic domain structures and have been considered to have normal rectangular or leaf-like shapes in standard ferromagnets such as Fe and Ni metals. We report on observations of constricted hysteresis loops in Fe and Ni single crystals with very low defect densities. The constricted loops were observed below T = 150 K and in a medium temperature range from 150 to 430 K in Fe and Ni single crystals, respectively. These constricted loops disappear by weak plastic deformation for both single crystals. The origin of constricted hysteresis loops was explained by eddy current effects under less domain wall pinning due to dislocations.

The validity of the Steinmetz law (P = KB n ) has been analyzed using the tanh model, by splitting the minor loops in three or two components, corresponding to dierent magnetization processes at dierent excitation levels. It is shown that the original Steinmetz law with the exponent n = 1.6 is valid only at and above the coercive eld, for intermediate and high induction values, where all the three magnetization processes are present. At small magnetization levels the exponent is about 3, much higher than the original proposed value.
