What is it about?
The measurement technique for the dielectric constant in matter under a very strong magnetic field has been developed. The potential control of the electric properties by a magnetic field will be widely developed by using this technique. Appearance of hidden ferroelectric phases may be discovered in many materials having strong spin, charge, and lattice degrees of freedom.

Why is it important?
There has never been a study on dielectric properties in matter in magnetic fields greater than 100 Tesla (1,000,000 Gauss). The developed technique has paved the way for a new research field direction.
Perspectives
This technique can be applied not only to multiferroics but also to potential ferroelectric materials by controlling electronic states with a very strong magnetic field.
