Both magnitude and frequency of alternating magnetic field (Hac) affect the magnetoelectric (ME) effect in a sputtered TbFe2/PZT/TbFe2 laminate composite. With the increase in Hac from 5 to 20 Oe, the magnitude of ME susceptibility (the ratio of induced electric polarization to Hac) is decreased indicating an insensitive polarization to the variation of Hac in this regime. When the frequency of Hac is lower than 2.5 kHz, the ME susceptibility is increased with increasing bias magnetic field (Hdc) up to 280 Oe. With further increases in Hdc, the ME susceptibility drops to a saturation value. By contrast, the ME susceptibility in the case of Hac beyond 2.5 kHz is monotonically increased by the increase in Hdc up to 4500 Oe. At 2.5 kHz, the ME effect has a linear variation with the Hdc ranging from 800 Oe to 4500 Oe..

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.
