Summary

Story summary

Researchers at the Max Planck Institute in Germany have developed a method to control ferroaxiality with circularly polarized light.
The approach uses terahertz light pulses to toggle the orientation of electric dipoles in ferroaxial materials.
The materials are immune to external magnetic interference, which could enable faster switching speeds and non-volatile memory.
However, practical use remains limited because the materials must be cooled to -70°C, requiring further research before commercialization.
