Magnetization and specific heat study on a SmCuAl3 single crystal

Characterization and Magnetic Properties of Heavy Rare-Earth A2Ir2O7 Pyrochlore Iridates, the Case of Tm2Ir2O7

“…In the second step, the CF parameters were again multiplied by Stevens factors for Yb 3+ and Tm 3+ . Also, see our previous work employing the same procedure . The two sets of scaled CF parameters and schemes for Tm 2 Ir 2 O 7 differ significantly (Table ).…”

“…Also, see our previous work employing the same procedure. 40 The two sets of scaled CF parameters and schemes for Tm 2 Ir 2 O 7 differ significantly (Table 2). The sets of CF parameters lead to different excitation energies in the single-ion magnetic response, including different singlet/doublet schemes.…”

Diversity in Crystal Structure and Physical Properties of RETX3 (RE – Rare Earth, T – Transition Metal, X – Main Group Element) Intermetallics

“…SmCuAl 3 is another system with a rare combination of ferro (28 K) and antiferromagnetic (6.6 K) ordering. [27] Antiferromagnetism: The compounds in the RETX 3 family reported for AFM ordering, their ordering temperature, and structure type are listed in Table 4. SmRuSn 3 shows AFM ordering at 6 K. The compound exhibits valence fluctuations due to two non-equivalent crystallographic sites for Sm, [124] which XPS and other measurements later confirmed.…”

“…The presence of 4 f electrons in RE and the d ‐electrons in T and their interaction favors the generation of interesting magnetic and electronic properties such as ferromagnetism, antiferromagnetism, [6–10] spin‐glass, [11] Kondo behavior, [8,12,13] heavy fermion behavior, [14,15] mixed valence, [16–18] and superconductivity [7,19–24] . Along with physical properties some solid‐state structural transformation, [18] narrow band gap semiconductor [16] The highly localized 4 f electrons in rare‐earth atoms in “many” intermetallic compounds [6,25–28] . In many cases, the 4 f electrons are partly delocalized, and the delocalized nature of s and p ‐electrons of X atom result in competition between Kondo behavior and RKKY (Ruderman‐Kittel‐Kasuya‐Yosida) interaction.…”

[6,[25][26][27][28] In many cases, the 4f electrons are partly delocalized, and the delocalized nature of s and p-electrons of X atom result in competition between Kondo behavior and RKKY (Ruderman-Kittel-Kasuya-Yosida) interaction. These interactions can be tuned by changing the concentration of conducting and localized electrons.…”
