Coexistence of localized magnetism and itinerant ferromagnetism in a Gd5Y2Pd3 single crystal

Magnetic and transport properties of Gd3Y4Pd3 single crystal

“…A strong negative curvature below T C for both the main crystallographic directions is observed. A very broad humps observed for Gd 3 Y 4 Pd 3 in the ferromagnetic state were also observed for other Gd 7−x Y x Pd 3 compounds with x = 0-4 [11][12][13][14][15].…”

“…Precise lattice parameter thermal variation measurements were carried out for the Gd 3 Y 4 Pd 3 and compared with those obtained earlier for the Gd 7−x Y x Pd 3 single crystals (see Table 1) [11][12][13][14][15]. The unit cell volume at 300 K for Gd 3 Y 4 Pd 3 is lower than for the compounds with higher gadolinium content and equals to 538.8 Å 3 , while for Gd 7 Pd 3 , Gd 6 YPd 3 , Gd 5 Y 2 Pd 3 , Gd 4 Y 3 Pd 3 volumes equal to 541.7 Å 3 , 542.5 Å 3 , 540.5 Å 3 , 540.1 Å 3 respectively.…”

“…The effect of substitution of gadolinium by nonmagnetic yttrium on the magnetism of Gd 7−x Y x Pd 3 (x = 0, 1, 2, 3) [11][12][13][14][15] were examined. With increasing Y-content the ferromagnetic transition shifts down to lower temperatures, namely whereas Gd 7 Pd 3 orders ferromagnetically below 334 K; Gd 6 YPd 3 , Gd 5 Y 2 Pd 3 , Gd 4 Y 3 Pd 3 and Gd 3 Y 4 Pd 3 undergo the magnetic transformation at 299 K, 263 K, 240 K and 197 K, respectively.…”

Influence of Yttrium Substitution οn the Electronic Structure and Magnetic Moment οf Gd7-xYxPd3(x = 0, 1, 2, 3, 4)

“…This enhancement indicates that also the Pd atoms carry a magnetic moment in [5,6] along the c axis, for Gd 6 YPd 3 the moment of 7.54 µ B for both the measured directions was found [6]. In the case of Gd 5 Y 2 Pd 3 the magnetization for both the axes attains practically the same value of 7.9 µ B [8]. In Gd 4 Y 3 Pd 3 magnetic moment was found to be 7.78 µ B for a axis and 7.64 µ B for c axis and in Gd 3 Y 4 Pd 3 the moment of 7.79 µ B was found for a axis and 7.69 µ B for c axis.…”

“…RM 2 (M = Al, Co, Ni), MnFe(P 1−x As x ), Mn(As 1−x Sb x ) and La(Fe 13−x Si x ) were reported [1,2]. Canepa et al [3] found the magnetocaloric effect for polycrystalline Gd 7 Pd 3 and ferromagnetic transition determined at T C = 323 K. The magnetic properties and temperature dependences of the lattice parameters of Gd 7 T 3 (T = Rh and Pd) and Gd 7−x Y x Pd 3 (x = 1, 2, 4) single crystals have already been reported [4][5][6][7][8]. These compounds crystallized in the same crystal structure type (Th 7 Fe 3 ) with the same c/a ratio of 0.63.…”
