Field-insensitive heavy fermion features and phase transition in the caged-structure quasi-skutterudite Sm${}_3$Ru${}_4$Ge${}_{13}$

Harikrishnan S. Nair, Kumar K. Ramesh, Douglas Britz +3

The robust field-insensitive heavy fermion features in Sm${}_3$Ru${}_4$Ge${}_{13}$ and the magnetic phase transition at $T_N\approx$ 5~K are studied using magnetization $M(T)$, specific…
