</script>Dielectric, thermal, electrocaloric, elastic, optical, and electromechanical properties of three ferroelectrics with diffuse phase transition (PLZT 8/65/35 ceramics, lead magnesium niobate and strontium barium niobate single crystals) are investigated in dependence on temperature and electric field strength. It is shown that a polar phase can be induced by an electric field within the nonpolar phase and vice versa, depending on whether the temperature is above or below Tt < TC. Analogies to stress-induced martensic transformations are emphasized. Dielektrische, thermische, elektrokalorische, elastische, optische und elektromechanische Eigenschaften von drei Ferroelektrika mit diffuser Phasenumwandlung (PLZT 8/65/35-Keramik, Bleimagnesiumniobat- und Strontiumbariumniobat-Einkristalle) werden in Abhangigkeit von der Temperatur und der elektrischen Feldstarke untersucht. Es wird gezeigt, das sich eine polare Phase durch ein elektrisches Feld innerhalb der unpolaren induzieren last und umgekehrt eine unpolare in einer polaren, je nachdem ob die Temperatur ober-oder unterhalb Tt < TC liegt. Auf Analogien zu spannungsinduzierten martensitischen Transformationen wird hinge wiesen.
