TL;DR: In this paper, a magnetic and Mossbauer spectroscopy study of nonoriented and magnetically oriented samples of Nd6Fe13Sn was performed and strong evidence for antiferromagnetic spin arrangements in the iron magnetic sublattice and antiferrome magnetism of the Nd moments with only a small contribution to the net magnetization in fields up to 14 T was found.
Abstract: A magnetic and Mossbauer spectroscopy study of nonoriented and magnetically oriented samples of Nd6Fe13Sn was performed. At 4.2 K a metamagnetic transition takes place in a field of 7.1 T. Strong evidence for antiferromagnetic spin arrangements in the iron magnetic sublattice and antiferromagnetism of the Nd moments with only a small contribution to the net magnetization in fields up to 14 T was found.

TL;DR: In this article, the high-field magnetization in RCu 2 (R=Ce, Pr, Nd, Sm, Dy, Tb and Ho) with the orthorhombic CeCu 2 -type crystal structure was studied.
Abstract: We studied the high-field magnetization in RCu 2 (R=Ce, Pr, Nd, Sm, Dy, Tb and Ho) with the orthorhombic CeCu 2 -type crystal structure. The field-induced metamagnetic transition due to the switching of the different magnetic anisotropy states was observed in RCu 2 (R=Ce, Pr, Dy and Tb). The origin of the transition is analyzed theoretically on the basis of the quadrupolar interaction and crystalline electric field.

TL;DR: In this article, a single crystal of UCr 2 Si 2 was grown for the first time, and the antiferromagnetic structure was determined by means of neutron diffraction, indicating the propagation vector (Q=[-\frac{1}{2},\frac{\frac{ 1}{2,0]\) and the magnetic moment 0.65µ B /U oriented along the [0,0,1] direction.
Abstract: We have grown a single crystal of UCr 2 Si 2 for the first time. UCr 2 Si 2 exhibits a structural transition from the ThCr 2 Si 2 -type ( I 4/ m m m ) to the triclinic structure ( P \bar1) below T a =210 K. The antiferromagnetic structure was determined by means of neutron diffractions, indicating the propagation vector \(Q=[-\frac{1}{2},\frac{1}{2},0]\) and the magnetic moment 0.65µ B /U oriented along the [0,0,1] direction. The high-field magnetization at 4.2 K indicates a metamagnetic transition at 11.4 T, reaching 0.65µ B /U at 14.9 T. The medium size of the electronic specific heat coefficient γ=80 mJ/K 2 mol, the magnetic entropy about half of R ln 2 at T N and a small effective moment 2.45µ B /U indicate that the antiferromagnetic state is due to 5 f -electrons with an itinerant character.

TL;DR: In this article, the authors presented magnetization data obtained on single crystals in fields up to 55 T applied in various crystallographic directions. But the results showed that the fixed-powder magnetization attains above MT a higher value than the free-powder sample.
Abstract: U 2 Pd 2 In exhibits antiferromagnetic (AF) order below T N =37 K with a non-collinear magnetic structure of U moments of ≈1.6 μ B /U confined to the basal plane of the tetragonal structure. At 4.2 K it exhibits a metamagnetic transition (MT) around 26 T. Previous high-field magnetization measurements on powder samples revealed that the fixed-powder magnetization attains above MT a higher value than the free-powder sample. The temperature dependence of susceptibility of a single crystal shows crossing of the basal plane and the c -axis signals below T N , the latter one dominating at low T . We present magnetization data obtained on single crystals in fields up to 55 T applied in various crystallographic directions. The observed magnetic anisotropy is attributed to the anisotropic 5f-ligand hybridization, which is forcing the U moments to orient in particular directions. The MT can be induced by a field applied within the basal plane but not in fields up to 55 T along the c -axis.
