Nontoxic lead free magnetoelectric composites NiFe2O4/0.948(K0.5Na0.5)NbO3-0.052LiSbO3 (NFO/KNN) with different NFO content were successfully prepared by a solid state reaction method. The dependence of ferroelectric, ferromagnetic properties and magnetoelectric coupling on NFO phase content was studied. The results show that the N F O content significantly affects the ferroelectric, ferromagnetic properties and ME effects. The ME behaviors are strongly dependent on the dc bias magnetic field. The ME voltage coefficients increase initially with the increase in dc magnetic fields and then decrease with further increase in the fields. A maximum magnetoelectric voltage coefficient of 5.59 mV·cm−1·Oe−1 is observed from the composite with 15 mol% NFO at the frequency of 1 kHz..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
