摘要

Colossal magnetoresistance (CMR) and colossal electroresistance (CER) induced by the electric field in spinel multiferroic CdCr₂ S ⁴ are reported. It is found that a metal-insulator transition in CdCr₂ S⁴ is triggered by the electrical field. In magnetic fields, the resistivity ρ of CdCr₂ S⁴ responds similarly to that of CMR manganites. Combing previous reports, these findings make CdCr₂ S⁴ 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.
