Combinatorial Exploration of Artificial Multiferroic Thin Films

Combinatorial functionality includes large throughput manufacture and rapid characterization of compositionally differing trials to hurry up the strategy of materials development. In this report, synthesis of composition distributes of artificial multiferroic thin film heterostructures composed of changing layers of (PTO) – (CFO) has become demonstrated using our combinatorial pulsed laser deposition (PLD) system. While in the spread samples, the typical composition changes continuously from pure PTO to genuine CFO so as we could notice the modifications in physical properties as the purpose of average composition. The coexistence of ferromagnetic and ferroelectric properties has been found in a huge extended region between pure CFO and PTO. Big surprise peak with the dielectric property has been observed in the center of multiplication, and it was recognized as the composition in which the ferroelectric phase transition transpires in PTO doped with CFO.
