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.

2023年8月14日 · 应用物理学杂志上发表了一篇题为“非中心对称三元碳化物GdCoC 2 中的奇特拓扑霍尔效应”的论文。 该论文报道了在GdCoC 2 中发现了一种奇特的拓扑霍尔效应（THE）。 GdCoC 2 在铁磁相变温度T C = 15.6 K下从顺磁态转变为铁磁态，然后在T t = 14.1 K下发生共格-非共格相变。 在T t 以下，外磁场和包括Dzyaloshinskii-Moriya相互作用在内的磁相互作用之间的竞争将产生具有非零标量自旋手征χ ijk 的特征自旋纹理，甚至是拓扑保护的自旋构型，从而诱导 …

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.

The crystal structure, magnetic properties and magnetocaloric effect (MCE) of GdCoC 2 have been studied. The compound crystallizes in an orthorhombic CeNiC 2-type structure which belongs to the Amm2 space group. A giant reversible MCE is observed in GdCoC 2 accompanied by a second-order paramagnetic to
