  As an advanced imaging system, the magneto-optical-electric joint-measurement
scanning imaging system (MOEJSI) brings spectroscopic techniques with unmatched
spatial resolution to very low temperature, high magnetic field and high
electric field measurements. It was developed for investigating the magnetic
and ferroelectric properties and their mutual control through
magneto-optical-electric joint-measurements, besides Raman and
photoluminescence features. In particular, the reflective magnetic circular
dichroism (RMCD) loops and imaging, linear dichroism (LD) imaging and
polarization-electric field hysteresis loop can be achieved when simultaneously
applied high magnetic field (7 T) and electric field (100 V) at low temperature
of 10 K.
