“…4. Heat capacity of the nonmagnetic La 2 Au 2 Cd up to 80 K was reported by us earlier, 27 and for the present study we have remeasured the same piece of the sample up to 150 K, to get the magnetic part of the heat capacity for Gd 2 Au 2 Cd. In the top panel of Fig.…”

“…These syntheses have to be carried out by induction melting, in a sealed tantalum or niobium crucibles, using high-frequency induction furnaces. [26][27][28][29] Using the synthesis method referred above, we have successfully synthesized Gd 2 Au 2 Cd which crystallizes in Mo 2 FeB 2 type structure ͑space group P4/mbm͒. We present the physical properties of this intermetallic herein.…”

Properties of the heavy-fermion spectrum in the canted phase of antiferromagnetic intermetallides

“…Such experiments, including those on heat capacity measurements in a magnetic field, have been performed with many AFM HF systems: PuGa 3 [2], Ce 2 Au 2 Cd [3], YbNiSi 3 [4], and PuPd 5 Al 2 [5]. The finding is that the magnetic field has a noticeable effect on the low-temperature heat capacity in the neighborhood of the Néel temperature.…”

Structure and magnetic properties of RE2Cu2Cd

“…Both compounds show intermediate-valent cerium [7,9]. 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.…”
