Multiferroic Compounds with Double-Perovskite Structures [PDF]
Materials, 2011 New multiferroic compounds with double-perovskite structures were synthesized. Bi2NiMnO6 was synthesized in bulk form by high-pressure synthesis and also in a thin-film form by epitaxial growth. The material showed both ferromagnetic and ferroelectric properties, i.e., the multiferroic property at low temperature.

Lead-free perovskite solar cells, what's next?
Next Energy, 2023 Although lead halide perovskite solar cells (PSCs) have achieved an efficiency of 25.7 %, the highly toxic composition, element lead, will hinder the use of PSCs in indoor photovoltaics, building-integrated photovoltaics and wearable devices.

Lead-free perovskite and double perovskite solar cells
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The toxicity and instability of lead-halide perovskite materials in the solar cells are yet demands must be resolved to vie to find alternatives of free lead-based halide perovskites and double perovskite materials. Here we report on the experimental synthesis of a new family of lead-free inorganic halide double perovskites ...
