Morphotropic Phase Boundary Enhanced Photocatalysis in Sm Doped BiFeO₃ [PDF]

Molecules, 2022
This paper presents the results of the synthesis of samarium-doped bismuth ferrite (BFO) nanoparticles by the solution combustion method. The dependence of BFO properties on the amount of the samarium (Sm) in the composition was studied.

Electric-field-induced phase transitions in co-doped Pb(Zr1−xTix)O3 at the morphotropic phase boundary [PDF]

Science and Technology of Advanced Materials, 2014
The strain- and polarization-electric field behavior was characterized at room temperature for Pb0.98Ba0.01(Zr1−xTix)0.98Nb0.02O3, 0.40 ≤ x ≤ 0.60. The investigated compositions were located in the vicinity of the morphotropic phase boundary, giving ...

Local-scale structures across the morphotropic phase boundary in PbZr1−xTixO3 [PDF]

IUCrJ, 2018
Lead zirconate titanate (PZT) is one of the most widely studied piezoelectric materials, mainly because of its `mysterious' relationship between the so-called morphotropic phase boundary (MPB) and its strong piezoelectric coupling factor.
