Magnetic properties of Gd(Fe_yAl_1-y)₃and (Gd_xY_1-x)Fe₃compounds

Influence of Fe substitution on the structure and magnetic properties in Gd(Ni1−xFex)3 intermetallic compounds

“…For higher x the Curie temperature decreases up to 725 K for the GdFe 3 compound (x = 1). The values of T C and T comp for the GdFe 3 compound are close to previously obtained [1,10,11]. The significant increase in DC (T) above 750 K for the GdFe 3 compound is related to the iron separation in high temperatures.…”

“…This value is quite small in contrary to the values observed before [4][5][6]. With the increasing iron concentration the value of transition magnetic moment increases and for the GdFe 3 compound equals to 1.8 B /Fe which is similar to the previously reported values [6,10,11].…”

“…The Ni/Fe substitution caused an increase in T C as well as a decrease in magnetic moment. In ferrimagnetic GdFe 3 compound (T C = 729 K) the existence of the compensation point between magnetic moments in Gd and Fe sublattices was evidenced at 618 K. The average magnetic moment per iron atom was evaluated as about 1.8 B [6,10,11].…”

Magnetic properties and magnetocaloric effect in Gd(Ni1−xCox)3 intermetallic compounds

“…The R-T compounds where R is rare earth and T is a transition metal show very interesting magnetic properties due to the combination of 3d itinerant and 4f localized magnetism [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. In such compounds we can distinguish the three kinds of interactions: R-R (4f-4f), R-T (4f-3d) and T-T (3d-3d).…”

Hyperfine interactions in R x Gd1− x Fe3 intermetallics R = Tb, Y

“…The series of the RFe 3 compounds where R is rare earth element exhibits very interesting magnetic properties due to the combination of 3d itinerant and 4f localized magnetism [1][2][3][4][5][6]. Moreover, they attracted a great deal of attention not only by the academics but also due to their possible application as permanent magnet materials.…”
