PlumX: Stabilization of the Ferroelectric Phase in Epitaxial Hf1–xZrxO2 Enabling Coexistence of Ferroelectric and Enhanced Piezoelectric Properties

Systematic studies on polycrystalline Hf_1–xZr_xO₂ films with varying Zr contents show that HfO₂ films are paraelectric (monoclinic). If the Zr content is increased, films become ferroelectric (orthorhombic) and then antiferroelectric (tetragonal). HfO₂ shows very good insulating properties and it is used in metal-oxide-semiconductor field-effect devices, while ZrO₂ shows good piezoelectric properties, but it is antiferroelectric. In between, Hf_0.5Zr_0.5O₂ shows good ferroelectric properties at the expense of poorer insulating and piezoelectric properties than HfO₂ and ZrO₂, respectively.

PlumX: Epitaxial Ferroelectric HfO2 Films: Growth, Properties, and Devices

About ten years after ferroelectricity was first reported in doped HfO₂ polycrystalline films, there is tremendous interest in this material and ferroelectric oxides are once again in the spotlight of the memories industry. Great efforts are being made to understand and control ferroelectric properties. Epitaxial films, which have fewer defects and a more controlled microstructure than polycrystalline films, can be very useful for this purpose. Epitaxial films of ferroelectric HfO₂ have been much less investigated, but after the first report in 2015 significant progress has been achieved.

The layered perovskite YBaCuFeO₅ (YBCFO) is considered one of the best candidates to high-temperature chiral multiferroics with strong magnetoelectric coupling. In RBaCuFeO₅ perovskites (R: rare-earth or Y) A-site cations are fully ordered whereas their magnetic properties strongly depend on the preparation process. They exhibit partial cationic disorder at the B-site that generates a magnetic spiral stabilized through directionally assisted long range coupling between canted locally frustrated spins.

In the quest for energy efficient and fast memory elements, optically controlled ferroelectric memories are promising candidates. Here, we show that, by taking advantage of the imprint electric field existing in the nanometric BaTiO₃ films and their photovoltaic response at visible light, the polarization of suitably written domains can be reversed under illumination. We exploit this effect to trigger and measure the associate change of resistance in tunnel devices.

Due to this strong magnetoelectric coupling, conceptually advanced ways for controlling antiferromagnetism become possible and it has been reported that electric fields and laser pulses can reversibly switch the antiferromagnetic order.
