Gd2Au2Cd: AMo2Fe

Abstract

The ternary intermetallic compound Gd 2 Au 2 Cd, synthesized by reaction of the elements via inductive melting, is studied for its structural and physical properties. Gd 2 Au 2 Cd crystallizes with the Mo 2 FeB 2 type ͑an ordered derivative of U 3 Si 2 structure͒, space group P4/mbm. The magnetic measurements ͑ac and dc suscep-tibility͒ establish magnetic ordering ͑T o ͒ at 110 K and have been confirmed by both transport ͑resistivity ;͒ and calorimetric ͑heat capacity, C͒ measurements. ac susceptibility measurements indicate "spin-glass" type anomalies below T o . The nature of magnetic ordering and the low-temperature behavior in this compound have been investigated in detail.

Ferromagnetic insulating and reentrant spin glass behavior in Mg doped La0.75Sr0.25MnO3 manganites

“…6 show that the low temperature peak in x 00 shifts toward lower temperature by the increase of ac magnetic field. Similar results have been reported by others, based on the Ac susceptibility data described above and these features are the signatures of the reentrant transition [21][22][23][24].…”

“…39 Such a coexistence of longrange order and spin glass has indeed been reported in many intermetallic compounds. [61][62][63][64] Figure 9͑a͒ shows the temperature variation of the zerofield heat capacity ͑C͒ of Ho 5 ͑Si 0.8 Ge 0.2 ͒ 4 . Adopting the method discussed by Gschneidner et al, 8 the nonmagnetic, i.e., the electronic and lattice contributions to the total heat capacity of Ho 5 ͑Si 0.8 Ge 0.2 ͒ 4 have been estimated using the prorated heat capacities of La 5 Si 4 and Lu 5 Si 4 ͓9% La 5 Si 4 and 91% Lu 5 Si 4 ͔.…”

Structure and magnetic properties of RE2Cu2Cd

“…Ce 2 Au 2 Cd contains stable trivalent cerium and can be considered as a heavy fermion system with antiferromagnetic ordering around 5 K [12]. Gd 2 Au 2 Cd exhibits ferromagnetism and spin-glass anomalies [13].…”

“…With cadmium, the series of RE 2 Ni 2 Cd (RE ¼ La, Ce, Pr, Nd, Sm, Tb, Dy) [7,8], RE 2 Rh 2 Cd (RE ¼ La, Ce, Pr, Nd, Sm) [9], RE 2 Pd 2 Cd (RE ¼ La, Ce, Nd) [6,10], Ce 2 Pt 2 Cd [6] and RE 2 Au 2 Cd (RE ¼ La, Ce, Pr, Nd, Sm, Gd) [11][12][13] compounds have been synthesized. The cell volumes of Ce 2 Ni 1.88 Cd and Ce 2 Rh 1.86 Cd strongly deviate from the Iandelli plots.…”
