Abstract

Provided herein are embodiments for adjusting a built-in bias of a media including a conductive layer and a ferroelectric layer above the conductive layer. In certain embodiments, a voltage signal is applied between the conductive layer of the media and an electrode (provided over at least a portion of the ferroelectric layer) to thereby tune the built-in bias so that the built-in bias moves in a direction of (i.e., towards) the desired built-in bias. In other embodiments, the temperature of the at least a portion of the ferroelectric layer of the media is elevated to thereby tune the built-in bias so that the built-in bias moves in a direction of (i.e., towards) the desired built-in bias. The desired built-in bias can be a zero built-in bias, or a non-zero built-in bias.
