AgCrSe2, a quasi-two-dimensional material, is famous for its superionic conducting. Here, it is confirmed that the anisotropic behaviors exist in the magnetic, electronic, and magneto-transport properties of the AgCrSe2 single crystal. A field induced phase transition causes asymmetrical antiferromagnetic states in the μ0H//ab plane and the c axis, which correspond to the positive/negative magnetoresistances in two directions, respectively. Below ∼32 K, a spin flop is manifested with a magnetic field of about 4 T, according to the field dependent electoral resistance. The anisotropic behaviors are ascribed to the quasi-two-dimensional structure and also to the unstable Ag+ ions and the puckered honeycomb lattice of Cr3+ ions. This research reveals fundamental transport properties in AgCrSe2 single crystals and can be explored further in superionic conductor engineering. [ABSTRACT FROM AUTHOR]

The temperature dependence of resistance of CrSiTe3 single crystals shows a cusp below the Cure temperature, which may be attributed to the disappearance of electron scattering on magnetic fluctuation. The magneto-conductance of CrSiTe3 was measured at temperatures ranging from 50 K to 30 K over the magnetic field range of 0–5 T. Magneto-transport measurements demonstrate that the low-field negative magneto-conductivity results from the weak anti-localization (WAL). The WAL effect was analyzed based on the Hikami-Larkin-Nagaoka (HLN) two-dimensional (2D) diffusive transport theory and the HLN equation could well fit the magneto-conductivity data.
