TL;DR: In this paper, the temperature dependence of the electrical resistivity, the magnetic susceptibility and the high-field magnetization of CeNi 2 Ge 2 was studied and it was shown that it exhibits metamagnetic behavior at H M ∼42 T as in CeRu 2 Si 2.
Abstract: We have studied the temperature dependence of the electrical resistivity, the magnetic susceptibility and the high-field magnetization of CeNi 2 Ge 2 . Quadratic temperature dependence of the resistivity is observed below 0.7 K. The susceptibility exhibits a broad maximum at 28 K. Magnetization shows metamagnetic behavior at H M ∼42 T as in CeRu 2 Si 2 . These results indicate that CeNi 2 Ge 2 is a new heavy-fermion compound showing the metamagnetic behavior in the nonmagnetic ground state.

TL;DR: In this article, a domain wall activation model is employed to obtain the parameters H0(0), 30kOe, VV(0)=0.24K−1, and β=0.016K− 1, where H0 is the coercive force at absolute zero, VT(0) the domain wall activations parameter, andβ the coefficient for the linear temperature dependence of the reduced anisotropy.

TL;DR: In this paper, the de Haas-van Alphen effect was investigated for the antiferromagnetically ordered compound GdIn 3, and the first time data on the dHvA frequencies and their angular dependencies were shown for magnetic field higher than the metamagnetic transition field.
Abstract: Results of the de Haas-van Alphen effect investigations are reported for the antiferromagnetically ordered compound GdIn 3 . For the first time data on the dHvA frequencies and their angular dependencies are shown for magnetic field higher than the metamagnetic transition field. The list of detected frequencies and related cyclotron masses is given. Among many Fermi surface branches observed, only the j, b and d correspond to theoretically predicted and experimentally observed branches for the nonmagnetic LaSn 3 . The metamagnetic transition taking place at 30 T in the GdIn 3 influences some branches of Fermi surface, mostly those in the (110) plane and close to the [111] direction. All effective masses found are lower than m 0 and close to those found for the LaSn 3 .

TL;DR: In this paper, the phase transition in Nd 0.6 Ca 0.4− x Sr x (Mn 1− y M y )O 3− γ (M=Cr, Ti) was investigated by measurement of magnetization and electrical transport in magnetic fields up to 12 T.

TL;DR: In this paper, two peaks in the differential magnetization at Hc1 and Hc2 are explained by the two-step metamagnetic transition model and the field dependent optical spectra are qualitatively explained by spin-cluster associated optical transitions appearing in the Ising spin network.
