TL;DR: In this article, the problem of nucleation for a metamagnetic phase transition of the first-order type is investigated and the results are compared with available experimental data, taking into account the magnetostatic energy.
Abstract: Magnetic phase diagrams, magnetization curves, and domain structures of a uniaxial two-sub-lattice metamagnet are considered taking into account the magnetostatic energy. The problem of nucleation for a metamagnetic phase transition of the first-order type is investigated. The results are compared with available experimental data.

TL;DR: In this paper, the influence of substitution of a small amount of Os (<2%) on the magnetism of the itinerant metamagnet UCoAl is studied on single-crystalline UCo1−xOsxAl compounds with x = 0.002, 0.005 and 0.01.
Abstract: The influence of substitution of a small amount of Os (<2%) on the Co sublattice on the magnetism of the itinerant metamagnet UCoAl is studied on single-crystalline UCo1−xOsxAl compounds with x = 0.002, 0.005 and 0.01. For x = 0.002, the ground state is still paramagnetic, like in UCoAl. The metamagnetic-transition field is 0.37 T, twice lower than in UCoAl. The compound with x = 0.005 is at the border between the paramagnetic and the ferromagnetic ground state. At T = 2 K, it is ferromagnetic, at elevated temperatures a magnetic field is necessary to maintain the magnetic state. In zero field, the ferromagnetic state vanishes at T = 8 K. The compound with x = 0.01 is a ferromagnet with strong uniaxial magnetic anisotropy similar to the previously studied compounds with x = 0.02–0.20.

TL;DR: The so-called Ising-axis conversion is an irreversible metamagnetic transition observed in the orthorhombic antiferromagnets RCu 2 (R = lanthanide ) in high magnetic fields applied along the hard axis of magnetization.
