Multifunctional materials based on the double-perovskite organic–inorganic hybrid (CH 3 NH 3 ) 2 [KCr(CN) 6 ] showing switchable dielectric, magnetic, and semiconducting behaviour

= 1.4(1) s at T = 2.0 K. The organic-inorganic hybrid, described above, can be considered a rare example of multifunctional materials which exhibit dielectric, magnetic, and conductive activities.
