Evidence of long-range ferromagnetic order and spin frustration effects in the double perovskite $L{a}_{2}CoMn{O}_6$

R. P. Madhogaria, R. Das, E. M. Clements +6

We present a comprehensive study on the magnetic structure, dynamics, and phase evolution in the single-phase double perovskite $L{a}_{2}CoMn{O}_6$. The mixed valence state due to oxygen…
