Ferromagnetic ordering of minority Ce${}^{3+}$ spins in a quasi-skutterudite Ce${}_3$Os${}_4$Ge${}_{13}$ single crystal

Om Prakash, A. Thamizhavel, S. Ramakrishnan

We report site disorder driven ferromagnetic ordering of nearly 8$\%$ Ce atoms in single crystalline Ce${}_3$Os${}_4$Ge${}_{13}$ below 0.5~K. Ce${}_3$Os${}_4$Ge${}_{13}$ crystallizes i…
