Materials Data on CrSbSe3 by Materials Project

SbCrSe3 is Orthorhombic Perovskite-like structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cr3+ is bonded to six Se2- atoms to form CrSe6 octahedra that share corners with five equivalent SbSe6 octahedra, edges with three equivalent SbSe6 octahedra, and edges with four equivalent CrSe6 octahedra. The corner-sharing octahedra tilt angles range from 17–67°. There are a spread of Cr–Se bond distances ranging from 2.51–2.62 Å. Sb3+ is bonded to six Se2- atoms to form distorted SbSe6 octahedra that share corners with five equivalent CrSe6 octahedra, edges with three equivalent CrSe6 octahedra, and edges with four equivalent SbSe6 octahedra. The corner-sharing octahedra tilt angles range from 17–67°. There are a spread of Sb–Se bond distances ranging from 2.69–3.28 Å. There are three inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 5-coordinate geometry to two equivalent Cr3+ and three equivalent Sb3+ atoms. In the second Se2- site, Se2- is bonded in a 3-coordinate geometry to one Cr3+ and two equivalent Sb3+ atoms. In the third Se2- site, Se2- is bonded in a 4-coordinate geometry to three equivalent Cr3+ and one Sb3+ atom.

Anisotropic magnetocaloric effect and critical behavior in CrSbSe3

In this work, we report anisotropic magnetocaloric effect and critical behavior in a quasi-one-dimensional ferromagnetic CrSbSe 3 single crystal. The maximum magnetic entropy change - Δ S M max is 2.16 J kg - 1 K - 1 for the easy a axis (2.03 J kg - 1 K - 1 for the hard b axis) and the relative cooling power RCP is 163.1 J kg - 1 for the easy a axis (142.1 J kg - 1 for the hard b axis) near T c with a magnetic field change of 50 kOe. The magnetocrystalline anisotropy constant K u is estimated to be 148.5 kJ m - 3 at 10 K, decreasing to 39.4 kJ m - 3 at 70 K. The rescaled Δ S M ( T , H ) curves along all three axes collapse onto a universal curve, respectively, confirming the second-order ferromagnetic transition. Further critical behavior analysis around T c ~ 70 K gives that the critical exponents β = 0.26 ( 1 ) , γ = 1.32 ( 2 ) , and δ = 6.17 ( 9 ) for H ∥ a , while β = 0.28 ( 2 ) , γ = 1.02 ( 1 ) , and δ = 4.14 ( 16 ) for H ∥ b . The determined critical exponents suggest that the anisotropic magnetic coupling in CrSbSe 3 is strongly dependent on orientations of the applied magnetic field.
