Antiferroelectric thin films phase diagrams

Phase diagrams in the Blume-Emery-Griffiths Ising thin films

We study the spin-1 Ising model with bilinear and biquadratic exchange interactions and single-ion crystal field. In addition to the four usual phases: disordered DIS, ferromagnetic FER, antiquadrupolar AQU and ferrimagnetic FRI, we found three new phases in the case of a thin magnetic film, namely: the sublattice A non magnetic phase NMA, the sublattice B non magnetic phase NMB and the global ...

Modeling of metastable phase formation diagrams for sputtered thin films

A method to model the metastable phase formation in the Cu-W system based on the critical surface diffusion distance has been developed. The driver for the formation of a second phase is the critical diffusion distance which is dependent on the solubility of W in Cu and on the solubility of Cu in W. Based on comparative theoretical and experimental data, we can describe the relationship between...

Phase diagrams of Bi1−xSbx thin films with different growth orientations

Phase diagrams and physical properties of single-domain epitaxial Pb„Zr1ÀxTix...O3 thin films

The equilibrium polarization states and physical properties of single-domain Pb(Zr12xTix)O3 ~PZT! thin films epitaxially grown on dissimilar cubic substrates have been examined by a nonlinear thermodynamic theory. In contrast to the former theoretical studies of PZT films, the two-dimensional straining and clamping of a film by a thick substrate is correctly taken into account in the reported c...

The effect of substrate clamping on the paraelectric to antiferroelectric phase transition in Nd-doped BiFeO3 thin films

Article history: Received 18 May 2016 Received in revised form 23 September 2016 Accepted 3 October 2016 Available online 4 October 2016 Thin films were deposited on Pt/Ti/SiO2/Si substrates using pulsed laser deposition from a target with a composition (Bi0.825Nd0.175Fe0.97Ti0.03O3) with 5 mol% excess Bi2O3 within the antiferroelectric (AFE) region of the NdFeO3-BiFeO3 phase diagram. However, ...
