Abstract
By studying the change of the current through stoichiometric undoped BaTiO
3
with time, we have examined whether the conductivity peaks of BaTiO

single crystals near the bulk phase transitions are due to a real conduction of electrons or holes through the samples or the fake current due to ferroelectric domain motion. The difference (Δ Q) between integrated current at temperatures (388 K and 400 K) above and below T
C
exceeds 2P
S
. The observation that at 2057s σ is still evidently enhanced shows that this effect is due to real conduction. Because the charge released by the switching cannot exceed 2P
S
≈ 35 μC/cm

at 388 K.
