La3Ni2SbO9 exhibits relaxor ferromagnetism below 105 K due to cation disorder. This perovskite-like compound shows spontaneous magnetization, but magnetic domains are too small for neutron diffraction detection.
Area of Science:
- Solid-state chemistry
- Materials science
- Magnetism
Background:
- Perovskite-like structures are crucial in materials science.
- Understanding magnetic properties of complex oxides is essential.
- Cation disorder can significantly influence material properties.
Purpose of the Study:
- Synthesize and characterize the novel compound La3Ni2SbO9.
- Investigate the magnetic behavior and crystal structure of La3Ni2SbO9.
- Determine the relationship between cation disorder and magnetic properties.
Main Methods:
- Standard ceramic synthesis method.
- Neutron diffraction for structural analysis.
- AC and DC magnetometry for magnetic characterization.
Main Results:
- La3Ni2SbO9 crystallizes in a monoclinic perovskite-like structure (P2(1)/n).
- Cation disorder observed with Ni(2+) and Sb(5+) sharing a site in a 1:2 ratio.
- Spontaneous magnetization detected below 105 K, indicative of ferromagnetism.
Conclusions:
- La3Ni2SbO9 exhibits relaxor ferromagnetism, analogous to relaxor ferroelectrics.
- Cation disorder leads to the formation of sub-neutron-diffraction-detectable magnetic domains.
- The material presents a unique case of magnetic ordering influenced by structural disorder.

Atomic Nuclei: Types of Nuclear Relaxation
In spin–lattice or longitudinal relaxation, the excited spins exchange energy with the surrounding lattice as they return to the lower energy level. Among several mechanisms that contribute to spin–lattice relaxation, magnetic dipolar interactions are significant. Here, the excited nucleus transfers energy to a nearby...
