Abstract
The magnetism of double perovskites is a complex phenomenon, determined from intra- or interatomic magnetic moment interactions, and strongly influenced by geometry. We take advantage of the complementary length and timescales of the muon spin rotation, relaxation, and resonance () microscopic technique and bulk ac/dc magnetic susceptibility measurements to study the magnetic phases of the double perovskite. As a result, we are able to discern and report ferrimagnetic ordering below and the formation of different magnetic domains above . Between , the following two magnetic environments appear, a dense spin region and a static-dilute spin region. The paramagnetic state is obtained only above . An evolution of the interaction between Ni and Re magnetic sublattices, in this geometrically frustrated fcc perovskite structure, is revealed as a function of temperature through the critical behavior and thermal evolution of microscopic and macroscopic physical quantities.
