Colossal magnetoresistance in the insulating ferromagnetic double perovskites Tl${}_2$NiMnO${}_6$: A neutron diffraction study

Lei Ding, Dmitry D. Khalyavin, Pascal Manuel +4

In the family of double perovskites, colossal magnetoresistance (CMR) has been so far observed only in half-metallic ferrimagnets such as the known case Sr${}_2$FeMoO${}_6$ where it ha…
