Abstract
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 [NH<sub>2</sub> (CH<sub>3</sub> )<sub>2</sub> ]<sub>n</sub> [Fe<sup>III</sup> Fe<sup>II</sup><sub>(1-</sub><sub>x</sub><sub>)</sub> Ni<sup>II</sup><sub>x</sub> (HCOO)<sub>6</sub> ]<sub>n</sub> (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.
