“…A giant spontaneous polarization was also observed in BFO films [ 3 ]. Size effects at the grain boundaries and in films at the boundary with the substrate also create an additional intermediate antipolar phase in BFO, which affects the microscopic mechanisms of current flow [ 9 ]. The nature of the influence of this phase on the transport properties is still unknown.…”

The paper considers how a film of bismuth ferrite BiFeO3 (BFO) is formed on a polymeric flexible polyimide substrate at low temperature ALD (250 °C). Two samples of BFO/Polyimide with different thicknesses (42 nm, 77 nm) were studied. As the thickness increases, a crystalline BFO phase with magnetic and electrical properties inherent to a multiferroic is observed. An increase in the film thickness promotes clustering. The competition between the magnetic and electrical subsystems creates an anomalous behavior of the magnetization at a temperature of 200 K. This property is probably related to the multiferroic/polymer interface. This paper explores the prerequisites for the low-temperature growth of BFO films on organic materials as promising structural components for flexible and quantum electronics.
