TL;DR: On the basis of the duality model, a semi-phenomenological and quantum-mechanical one which takes into account the dual nature of itinerant and localized characters of f-electrons, the systematics of metamagnetic behavior in the paramagnetic phase and the appearance of weak antiferromagnetism with extremely small ordered moment of =10 − μ B are shown in this article.

TL;DR: In this paper, high field magnetization and magnetoresistance of a single crystal UPd 2 Al 3 were investigated up to 50 Tesla and a sharp metamagnetic magnetization was observed in the c-plane at 18 T.
Abstract: High field magnetization and magnetoresistance of a single crystal UPd 2 Al 3 are investigated up to 50 Tesla (T) and a sharp metamagnetic magnetization is observed in the c -plane at 18 T. The metamagnetism is explained by assuming the magnetization-dependent heavy fermion energy.

TL;DR: The magnetocaloric properties of powder samples of the monoclinic YFe2H4.2, YFe 2D4.4, and Y0.5Tb0.2 compounds have been studied at their itinerant electron metamagnetic transition.
Abstract: The magnetocaloric properties of powder samples of the monoclinic YFe2H4.2, YFe2D4.2, and Y0.5Tb0.5Fe2D4.2 compounds have been studied at their itinerant electron metamagnetic transition (TM0=131, 84, and 127 K, respectively). Large reversible entropy changes are observed, up to −ΔSM=10.83 J K−1 kg−1 for a field variation of 5 T in YFe2D4.2, making these alloys candidates for magnetic refrigeration applications. The results are compared with previously published data on other potential magnetic refrigerants with itinerant electron metamagnetic transitions.

TL;DR: In this paper, the magnetic field-induced metamagnetic transition in Ce(Fe0.96Ru0.04)2 alloys was investigated and it was shown that the isothermal virgin magnetization curve lies outside the envelope magnetization curves obtained in subsequent field cycles.
Abstract: We present results of dc magnetization measurements investigating the magnetic field-induced metamagnetic transition in Ce(Fe0.96Ru0.04)2. In the temperature region where this material undergoes a ferromagnetic to antiferromagnetic first-order phase transition, the isothermal virgin magnetization curve lies distinctly outside the envelope magnetization curve obtained in the subsequent field cycles. We show that this anomalous behaviour of the virgin magnetization curve arises due to the dependence of the initial zero field magnetic state on the temperature–field history of the sample in the concerned temperature regime. This origin of the anomalous virgin magnetization curve is distinctly different from the very similar behaviour observed earlier in Al- and Os-doped CeFe2 alloys, where this feature was associated with the kinetic arrest of the first-order ferromagnetic to antiferromagnetic transition.

TL;DR: In this article, the influence of two treatments, high-temperature annealing and grinding, on the phenomenon of metamagnetic transition was investigated. But the results provided us with information about the origin of these jumps in magnetization.
Abstract: Substitutions in the Mn sublattice of antiferromagnetic, charge, and orbitally ordered manganites was recently found to produce intriguing metamagnetic transitions consisting of a succession of sharp magnetization steps separated by plateaus. The compounds exhibiting such features can be divided into two categories, depending on whether they are sensitive to thermal cycling effects or not. One compound in each category has been considered in the present study. This article reports on the influence of two treatments: high-temperature annealing and grinding. It is shown that both of these treatments can dramatically affect the phenomenon of magnetization steps. The results provide us with information about the origin of these jumps in magnetization.
