Tailoring the magnetocaloric, magnetic and thermal properties of Dy6(Fe,Mn)X2 intermetallics (X Sb, Te, Bi)

Selecting optimal R6TX2 intermetallics (R = Gd, Tb, Dy; T = Mn, Fe, Co, Ni; X = Sb, Te) for magnetic refrigeration

“…2(b and d)), while a change in the p-block element has only shown to have a minor effect on the position of the Curie temperature. [29][30][31] Three general trends regarding the effect of the c cell parameter on the Curie temperature have been detected in this study. On one hand, the three compounds with a larger c cell parameter, which are the ones with Dy 4 and Sb 2 in their composition (compounds 2, 3, and 4 as labelled in Table 1), show a linear increase of T C following the c cell parameter (see Fig.…”

“…This behavior has already been observed in our previous studies on this family, with a greater effect on compounds containing Tb and Dy. 30,31 T C and T m are precisely indicated by the position of the peaks in the real part of ac susceptibility, as shown in the lower (c) and (d) graphs of Fig. 2.…”

Magnetic Properties, Magnetocaloric and Magnetoresistance Effects in Gd5In3 and Tb5In3 Compounds

“…In the present study, we have carefully investigated the structural, magnetic, and transport properties of the RE-based intermetallic compounds Gd 5 In 3 and Tb 5 In 3 . Both the samples show multiple magnetic transitions, [52][53][54] where the samples order ferromagnetically at a higher temperature (200 and 160 K, respectively) followed by the entry into an AFM-like state and/or spin-canted state at lower temperatures (90 and 50 K, respectively). Gd 5 In 3 has higher FM ordering temperature compared to Tb 5 In 3 .…”

Magnetocaloric Properties in Gd3Ni2 and Gd3CoNi Systems

“…To estimate the zero-field spontaneous magnetization, M s , we have a look on the expression of the magnetic entropy from the mean-field theory [9]:…”

“…The optimization and development of magnetic refrigerator devices depend on a solid thermodynamic description of the magnetic material, and its properties throughout the steps of the cooling cycles [6,7]. Among these magnetic systems, intermetallic alloys formed by rare earth (R) and transition metal (M) such as Gd 3 Ni 2 ,Lu 2 Pd 5 and Nd 2 Co 1.7 [8][9][10]. The projected applications of these materials include magnetic refrigeration, magnetic memory, spintronics and magnetic sensors, etc.…”
