A magnetic field of 3.5 kOe induced a giant magnetodielectric ͕MD= ͓Ј͑H͒ − Ј͑0͔͒ / Ј͑0͖͒ response, of 1800% at f = 7 MHz, at room temperature. The ferrite exhibits a large magnetic field-induced frequency response of 180 Hz/Oe. We suggest that this effect arises primarily from a spin-dependent space charge polarization mechanism in response to the application of dc magnetic fields.
