Scientific Achievement
Scheelite-type DyCrO4 has a low field collinear antiferromagnetic phase with a large linear magnetoelectric effect, with a transition to a high field multiferroic canted antiferromagnetic phase with a sizeable magnetic moment.
Significance and Impact
The work relates the underlying magnetic structure to magnetoelectric effects that have many potential applications, for example in spintronic devices, nonvolatile memories, and high-sensitivity sensors.
Research Details
- The temperature and field dependence of magnetoelectric and ferroelectric properties were characterized using standard bulk techniques.
- Neutron diffraction was used to determine the magnetic structures and transitions at different magnetic fields and temperatures.
