摘要：

Electron emission induced by the reversal of polarization in BaTiO3 crystals grown by pulling method have been investigated in the 370-410 K temperature range The electrons are emitted mainly during every second half-period of the electric a.c. switching field. Anomalies of the temperature dependences of the electron emission intensity at about 10 K below T(c) and at T(c) have been observed. The possible mechanism of this electron emission is discussed.
