Abstract: Colossal magnetoresistance (CMR) and colossal electroresistance (CER) induced by the electric field in spinel multiferroic CdCr(2)S(4) are reported. It is found that a metal-insulator transition in CdCr(2)S(4) is triggered by the electrical field. In magnetic fields, the resistivity rho of CdCr(2)S(4) responds similarly to that of CMR manganites. Combing previous reports, these findings make CdCr(2)S(4) the unique compound to possess all four properties of the colossal magnetocapacitive, colossal electrocapacitive, CER, and CMR. The present results open a new venue for searching new materials to show CMR by tuning electric and magnetic fields.
