Crystal Structure

Structural property summary

  • Single crystal form: dark gray, metallic luster, square/rectangle facets
  • Structure type: Layered, P4/nmm (may undergo orth. distortion in case of Sb deficiency)
  • Air sensitivity: Bulk – light; Nano flake – moderate

Transport Properties

Resistivity- Temperature dependence

  • Non-metallic

Hall effect

e-type

Magnetic Properties

Magnetization- Temperature dependence

Note: Antiferromagnetic below 2.7 K

Magnetization- Magnetic field dependence

Note: Metamagnetic transitions (Hc1 and Hc2 in the figure)

Specific Heat

Specific Heat (C/T vs T)

Electronic structure

Top: ARPES equal energy surfaces
Bottom: Calculated equal energy surfaces

 

ARPES band dispersion

The lack of photon energy dependence indicates two-dimensionality

The above results are reported in our paper: “Magnetic Topological Semimetal Phase with Electronic Correlation Enhancement in SmSbTe”, Advanced Quantum Technologies, 2100063 (2021)
