Manipulation Of Magnetic Field On Dielectric Constant And Electric Polarization In Cr2wo6

The magnetic, dielectric, and magnetoelectric properties are investigated in the polycrystalline Cr2WO6. Under zero magnetic fields, no dielectric anomaly and electric polarization are observed in this compound. After magnetoelectric annealing, the magnetic-field-induced dielectric and pyroelectric current peaks simultaneously present around its Neel temperature and increase with increasing magnetic field, showing large magneto-dielectric and linear magnetoelectric effects in Cr2WO6. The origin of magnetoelectric effect in this compound is discussed. (C) 2014 AIP Publishing LLC.
