Magnetic transition in the $J_{eff} = 1/2$ Kagomé system Sm $_{3}$ Sb $_{3}$ Zn $_{2}$ O $_{14}$

Vinod Kumar, S. Kundu, M. Baenitz +1

We present a study of Sm $_{3}$ Sb $_{3}$ Zn $_{2}$ O $_{14}$ (SSZO) through magnetization and specific heat capacity $C_{p} (T)$ measurements. SSZO contains well separated planes of Sm $^{3 +}$ mag…

Failure to achieve the $J_{e f f}$ ~=~0 state even in nearly isolated Ir $^{5 +}$ in Sr $_{3}$ NaIrO $_{6}$ : are iridates enough for realizing true $j$ - $j$ coupling?

Abhisek Bandyopadhyay, Atasi Chakraborty, Sayantika Bhowal +11

Spin-orbit coupling (SOC) often gives rise to interesting electronic and magnetic phases in an otherwise ordinary pool of paramagnetic heavy metal oxides. In presence of strong SOC…
