“…There is almost no sudden change of r and tan s in the frequency range up to 100 kHz. The r decreases gradually with increasing frequency, but the tan s of r for Bi 3.15 Nd 0.85 Ti 3 O 12 films is larger than the value of BZT films[15], so Bi 3.15 Nd 0.85 Ti 3 O 12 films have more promising potential to substitute the BZT films which are attractive lead-free dielectric material for dynamic random access memories[16].
