2024年9月1日 · Our main findings are: (1) GdCoC crystallizes in a simple layered tetragonal structure with P4 2 /mmc space group; (2) the GdCoC compound undergoes two successive FM transitions at T C2 of 10.9 K and T C1 of 14.8 K along with a low temperature weak AFM transition with T N of 7.6 K under low magnetic fields, whereas only a single broad ...

1996年8月1日 · GdCoC 2 is an antiferromagnet below T N = 15.6 K and shows an order-order transition at T t = 14.0 K. The measurements of 155 Gd Mössbauer effect and magnetization process reveal that the Gd moments align noncollinearly by an angle of 48° from the a …

2024年12月1日 · We have fabricated four single-phase Sr RE2 O 4 (RE = Gd, Dy, Ho, Er) oxides and conducted a systematic experimental investigation into their structural, magnetic, and low-temperature MC properties. All these Sr RE2 O 4 oxides crystallize in an orthorhombic structure (space group Pnma) and exhibit typical geometrical frustration.

A giant reversible MCE is observed in GdCoC 2 accompanied by a second-order paramagnetic to ferromagnetic (PM–FM) phase transition around the Curie temperature ∼15 K. For the magnetic field change of 0–5 T, the maximum values of the magnetic entropy change (−Δ S max M ), relative cooling power (RCP), and refrigerant capacity (RC) are ...

GdCoC crystallizes in the tetragonal P4_2/mmc space group. The structure is three-dimensional. Gd3+ is bonded to four equivalent C4- atoms to form a mixture of distorted corner and edge-sharing GdC4 tetrahedra. All Gd–C bond lengths are 2.53 Å. Co1+ is bonded in a linear geometry to two equivalent C4- atoms. Both Co–C bond lengths are 1.81 Å.

We have herein provided a systematic investigation of the crystal structure, microstructure, electronic structure, magnetic phase transition, critical behavior, and MCE of the GdCoC compound featuring excellent cryogenic magnetocaloric performance by means of experimental determination and theoretical calculation.
