Holographic recording and erasure experiments in Cd13P4S22I2 crystals are reported. The refractive index change of the volume phase hologram is larger than Δn=1.5×10−4, whereas the static dielectric constant of this reversible storage medium is only about 10. These are rather unusual properties if compared with electrooptic KNbO3.
