Magnetic structure of the Zr6CoAs2-type Tb6FeBi2 compound

Thermomagnetic properties near transitions of Tb6FeX2 (X=Sb, Bi)

“…l89). The result agrees well with that of the literature [2]. The lattice parameters of two compounds Tb 6 FeSb 2 and Tb 6 FeBi 2 are given in Table 1.…”

“…It has been shown that heavy-rare-earth elements and their compounds are the promising potential materials for finding a large magneto-caloric effect due to their high magnetic moments. In our previous work [1], our group has studied the structure and magnetic properties of a new compound Tb 6 FeSb 2 with a Curie temperature of 256 K. Morozkin et al [2] also reported the isostructural compound Tb 6 FeBi 2 with the Curie temperature at 250(5) K. The sharp changes in magnetization of two compounds at T c motivated us to study the magnetic behaviors and thermomagnetic properties which allow the estimation of the magneto-caloric effects in this system. Here, we presented the results.…”

Structure and magnetic behaviors of Gd 6 FeBi 2 compound

“…Meanwhile, Morozokin has also got R 6 FeSb 2 (R ¼ Sc, Y, Lu, Dy, Ho, Er, Tm) and R 6 FeBi 2 (R ¼ Y, Lu, GdeDy, Er, Tm) compounds during their systemic investigation on ternary R-based compounds [5,6]. Recent studies on the magnetic behaviors of such compounds indicated that Tb 6 FeX 2 (X ¼ Sb, Bi) showed a Curie temperature approaching room temperature and large magnetocaloric effect (MCE) [7,8]. It is well known that Gd-based compounds show large MCE, which motivated us to investigate the structure and magnetic behaviors of Gd 6 FeX 2 (X ¼ Sb, Bi).…”

Crystal structure and magnetic properties of Tb6FeSb2

“…In order to obtain special magnetic properties by adding antimony element into Ho-Fe alloys, our group studied the phase relationship of the Ho-Fe-Sb system [2] and determined a new ternary compound Ho 6 FeSb 2 [3]. Morozkin et al reported on the crystal structure and magnetic properties of Tb 6 FeBi 2 [4]. Recently we studied the crystal structure and magnetic properties of Tb 6 FeSb 2 compound and the results are presented here.…”
