TL;DR: In this article, the authors introduced the model that the heavy fermion state is destroyed by the magnetic field and the exchange frustration among the field-induced f-electron moments gives the successive transitions.

TL;DR: In this paper, the authors have successfully grown single crystals of CeAu 2 Si 2 with the Neel temperature of 8.1 K. The magnetic properties are very anisotropic in the antiferromagnetic state as well as in the paramagnetic state.
Abstract: We have successfully grown single crystals of CeAu 2 Si 2 with the Neel temperature of 8.1 K. The magnetic properties are very anisotropic in the antiferromagnetic state as well as in the paramagnetic state. When a field is applied parallel to the c -axis, the single crystal exhibits a sharp metamagnetic transition of first order at 4.2 T, while the magnetization increases almost linearly with fields parallel to the a -axis.

TL;DR: In this article, the authors present the first study of radio-frequency transverse susceptibility (TS) of bulk ErCo2 using a self-resonant tunnel-diode oscillator technique.
Abstract: ErCo2 represents a typical example of magnetism of itinerant electron systems and metamagnetic processes and has been the subject of extensive research. We present here the first study of radio-frequency transverse susceptibility (TS) of bulk ErCo2 using a self-resonant tunnel-diode oscillator technique. TS measurements reveal the collective magnetic switching of the Er moments at temperatures below the ferrimagnetic transition temperature, Tc∼32 K, and the existence of Co nanoclusters with short-range correlations at Tc

TL;DR: In this paper, a new model of metamagnetic phase transition with temperature in Mn3GaC was proposed, which takes into account two independent strains (trigonal and isotropic ones) as functions of temperature, calculated similarly to the microscopic theory of magnetostriction.
Abstract: A new model of metamagnetic phase transition with temperature in Mn3GaC is proposed. The magnetoelastic Hamiltonian takes into account two independent strains (trigonal and isotropic ones) as functions of temperature, calculated similarly to the microscopic theory of magnetostriction. Necessary conditions for the transition are established within the molecular field approximation and the fit with experiment is discussed.
