Summary:

A giant room-temperature magnetodielectric (MD) response upon the application of a small magnetic field is of fundamental importance for the practical application of a new generation of devices. Here, the giant room-temperature magnetodielectric response is demonstrated in the metal–organic framework (MOF) of [NH2(CH3)2]n[FeIIIFeII(1−x)NiIIx(HCOO)6]n (x ≈ 0.63–0.69) (1)with its MD coefficient remaining between −20% and −24% in the 300–410 K temperature range, even at 0.1 T. Because a room-temperature magnetodielectric response has never been observed in MOFs, the present work not only provides a new type of magnetodielectric material but also takes a solid step toward the practical application of MOFs in a new generation of devices.
