Magnetoelectric (ME) materials composed of magnetostrictive and piezoelectric phases have been the subject of decades of research due to their versatility and unique capability to couple the magnetic and electric properties of the matter. While these materials are often studied from a fundamental point of view, the 4.0 revolution (automation of traditional manufacturing and industrial practices, using modern smart technology) and the Internet of Things (IoT) context allows the perfect conditions for this type of materials being effectively/finally implemented in a variety of advanced applications. This review starts in the era of Rontgen and Curie and ends up in the present day, highlighting challenges/directions for the time to come. The main materials, configurations, ME coefficients, and processing techniques are reported.

Magnetoelectrics: Three Centuries of Research Heading towards the 4.0 Industrial Revolution.

Magnetoelectric laminate composites of piezoelectric-magnetostrictive materials were investigated. The composites were prepared by stacking and bonding Pb(Zr, Ti)O3 (PZT) and Terfenol-D disks. Experimental results indicated that the magnetoelectric voltage coefficient, dE/dH, increased with decreasing thickness and increasing piezoelectric voltage constant (g31) of the PZT layer. We obtained the highest magnetoelectric voltage coefficient of 4.68 V/cmOe at room temperature for the sample with high g33 PZT of 0.5 mm in thickness. This value is about 36 times higher than the best reported value.

Particulate contaminants are common damage precursors on optics in the daily operation of high laser power systems. In this paper, the damage behaviors of silica particles attached to the front and back surfaces of fused silica optics under the irradiation of a 355 nm laser were studied. Results showed that silica particles on the front surface tend to splash severely under high fluence, while the particle on the back surface forms a large laser-induced shallow pit (LSP)-like pit on the substrate. Different damage morphologies were observed, and damage mechanisms were also proposed.
