Special Issue Information

Dear Colleagues,

We live in an era of rapid and strong impact advances in science and technology, where scientific and innovation areas are increasingly overlapping in new and exciting ways, for the benefit of society. Recent technological advances point towards the development of sustainable, wireless, and interconnected autonomous smarter devices, systems, and cities, which are strongly based on the development of smart and multifunctional materials.

In this way, developing new smart and multifunctional materials and exploring their applicability has been the focus of an increasing number of areas, such as in the fields of materials, sensors, actuators, and biomedical applications, among others. Smart and multifunctional materials are benefitting from of this understanding and control of their physico-chemical properties, leading to a suitable tailoring of processability and device integration, shape/morphology, and performance.

In recent decades, multiferroic and magnetoelectric concepts have changed accepted thinking in this regard, resulting in a new generation of high-performance materials that have led to an increased focus on controlling production, structures, and functional responses, as well as on implementation in proof-of-concept applications. Multiferroics and magnetoelectrics have become hot topics in the increasingly scientific and technologically relevant world of smart and multifunctional materials due to the possibility of controlling the electric response with the magnetic field and vice-versa. Sensors, actuators, biomedical scaffolds, four-state memories, and energy harvesters are just some examples of applications that have been reported in recent times.

Despite the progress experienced by the research community in these areas being intense and fruitful, the main issues that should be addressed in order to enable real applications still need to be discussed and are related to improved performance, a deeper understainding of the physico-chemical characteristics of the mateirials, processability, device integration, and reliability. It seems noticeable that open questions and challenges are unceasingly emerging, which also act as a never-ceasing fountain of future research ideas and applications.

It is our pleasure to invite you to submit a manuscript for this Special Issue that seeks to become a landmark in the development of this interesting and fruitfull reseach field. Review papers, full papers, and short communications are all welcome.

Structural, Magnetic and Optical Properties of Gd and Co Co-Doped YFeO3 Nanopowders

Abstract
YFeO3, YFe0.95Co0.05O3, Y0.95Gd0.05FeO3 and Y1−xGdxFe0.95Co0.05O3 (x = 0.0, 0.05, 0.10, 0.15 and 0.20) nanopowders were successfully fabricated via a low-temperature solid-state [...] Read more.
YFeO3, YFe0.95Co0.05O3, Y0.95Gd0.05FeO3 and Y1−xGdxFe0.95Co0.05O3 (x = 0.0, 0.05, 0.10, 0.15 and 0.20) nanopowders were successfully fabricated via a low-temperature solid-state reaction technique. Results obtained using X-ray diffraction (XRD), scanning electron microscopy (SEM), and Raman spectra indicate that YFeO3 nanopowders with Gd3+ and Co3+ ions co-doping at Y and Fe-sites were fabricated at 800 °C in sizes below 50 nm, and a distorted structure was obtained. Magnetic hysteresis loop analyses illustrate that ferromagnetic behavior of YFeO3 nanopowders can be enhanced with the addition of Gd and Co. Whereas the maximum and remnant magnetization of the powders were found to be about 5.24 and 2.6 emu/g, respectively, the optical band gap was around 2.4 eV, proving that co-doped YFeO3 nanopowders have a strong capability to absorb visible light. Because both magnetic and optical properties of these materials are greatly improved with the addition of Gd and Co, one can expect the scope of their potential application in the magnetic and optical fields to increase.
