TL;DR: In this paper, the magnetic properties of Ce 2 CuGe 6 and Pr 2CuGe 6, both of which exhibit a ferrimagnetic order around 15 K, were reported. But they were not shown to have a small residual magnetization, and the peak of specific heat and sharp decrease of electrical resistivity near their ordering temperature are consistent with observed magnetic orders.
Abstract: We report the magnetic properties of Ce 2 CuGe 6 and Pr 2 CuGe 6 , both of which exhibit a ferrimagnetic order around 15 K. Hysteretic curves with small residual magnetization, 7.8×10 -4 µ B / f.u. and 1.1×10 -2 µ B / f.u., are observed for Ce 2 CuGe 6 and Pr 2 CuGe 6 , respectively. The peak of specific heat and the sharp decrease of electrical resistivity near their ordering temperature are consistent with observed magnetic orders.

TL;DR: In this paper, the magnetic properties of indium-flux grown single crystals of EuIr2Ge2 using electrical resistivity, magnetization, specific heat, magnetoresistance and 151Eu M?ssbauer spectroscopy were analyzed.
Abstract: We present a complete characterization of the magnetic properties of indium-flux grown single crystals of EuIr2Ge2 using electrical resistivity, magnetization, specific heat, magnetoresistance and 151Eu M?ssbauer spectroscopy All results indicate that Eu ions in EuIr2Ge2 are in the divalent state with Eu moments ordering antiferromagnetically at TN = 205?K While at higher temperatures the susceptibility ? is isotropic as expected for the pure spin nature of the Eu local moment, below 40?K a pronounced anisotropy emerges, with ?ab in the basal plane being a factor of two larger than ?c along c at TN We observed a pronounced metamagnetic transition in the in-plane magnetization, which is also reflected in a step-like increase of the magnetoresistance Further analysis of the data indicates that the metamagnetic transition is related to a spin?flop transition The origin of this strong anisotropy and of the pronounced metamagnetic transition is discussed

TL;DR: In this article, an investigation of La and Ca doped Sr4Ru3O10, featuring a coexistence of interlayer ferromagnetic and intralayer metamagnetism, is presented.
Abstract: An investigation of La and Ca doped Sr4Ru3O10, featuring a coexistence of interlayer ferromagnetism and intralayer metamagnetism, is presented. La doping readily changes magnetism between ferromagnetism and metamagnetism by tuning the density of states. It also results in different Curie temperatures for the c-axis and the basal plane, highlighting a rare spin-orbit coupling with the crystal field states. In contrast, Ca doping enhances the c-axis ferromagnetism and the magnetic anisotropy. La doping also induces a dimensional crossover in the interlayer transport whereas Ca doping exhibits a tunneling magnetoresistance and an extraordinary T 3/2 dependence of the resistivity. The drastic changes caused by the doping demonstrate a rare borderline magnetism that is delicately linked to the interplay of the density of states and spin-orbit coupling.

TL;DR: In this article, powder X-ray-diffraction measurements on MnFeP 0.46 As 0.54 in fields up to 5 T in the temperature range 8-310 K were performed.
Abstract: We have performed powder X-ray-diffraction measurements on MnFeP 0.46 As 0.54 in fields up to 5 T in the temperature range 8–310 K. The compound which has the hexagonal Fe 2 P type of structure shows a field-induced isostructural phase transition. We found that the cell volume decreases slightly and continuously with increasing magnetic field, although the lattice parameter ratio c/a drastically changes. A tentative analysis of the dependence of the lattice parameters on the magnetization has been carried out using the extended Bean–Rodbell model.
