Magnetic, thermal and electrical properties of Er3Co studied on single crystals

Spin fluctuations induced by f–d exchange in R3T compounds

“…The R 3 M compounds have the highest R content and crystallize in the orthorhombic Fe 3 C type structure when M is a d-transition metal with an almost full d-band. These compounds exhibit a rich variety of field-and temperature-induced magnetic phase transitions [1]. The fact that the M-ions in the Fe 3 C-type lattice are surrounded by rare earth ions together with the large distance between M-ions ðB4 ( AÞ results in a significant 5d(R)-d(M) hybridization [2] and implies a strong influence of 4f-electrons on the delectrons of the transition metal, even though the latter do not possess ordered magnetic moments in R 3 M: The present paper discusses the interplay between the R-and M-electronic subsystems of R 3 M and its influence upon the heat capacity and electrical resistivity.…”

Crystallographic and magnetic descriptions of a novel erbium rich aluminide: Er10Co1+xAl3−x (x = 0.30)

“…Complex magnetic structures with spin reorientations are observed in erbium rich based intermetallics as in the case of e.g. the previously mentioned Er 3 Co [30] and Er 3 Ni 2 [5].…”

The physical properties of Gd3Ru: A real candidate for a practical cryogenic refrigerator

“…In this case, we used c ¼ 50 mJ/ mol K and 130 K h D 150 K, which are consistent with other R 3 M results. 10,24 This analysis reveals that only a fraction of the Gd magnetic entropy of Gd 3 Ru (3Rln(8) ¼ 52.1 J/ mol K) is released at T C , around 20 J/mol K for h D ¼ 130 K (or 34 J/mol K for h D ¼ 150 K). In fact, the Gd 3 M (M ¼ Ni, Co, and Rh) compounds present a similar behavior where the magnetic entropy at T ord is about 60% of the full value and it is argued that the remaining part is associated to short range correlations between the Gd ions.…”
