Materials science is recognized as one of the main factors driving development and economic growth. Since the silicon industrial revolution of the 1950s, research and developments in materials and solid state science have radically impacted and transformed our society by enabling the emergence of the computer technologies, wireless communications, Internet, digital data storage, and widespread consumer electronics. Today's emergent topics in solid state physics, such as nano-materials, graphene and carbon nano-tubes, smart and advanced functional materials, spintronic materials, bio-materials, and multiferroic materials, promise to deliver a new wave of technological advances and economic impact, comparable to the silicon industrial revolution of the 1950s. The surge of interest in multiferroic materials over the past 15 years has been driven by their fascinating physical properties and huge potential for technological applications. This article addresses some of the fundamental aspects of solid-state multiferroic materials, followed by the detailed presentation of the latest and most interesting proposed applications of these multifunctional solid-state compounds. The applications presented here are critically discussed in the context of the state-of-the-art and current scientific challenges. They are highly interdisciplinary covering a wide range of topics and technologies including sensors, microwave devices, energy harvesting, photo-voltaic technologies, solid-state refrigeration, data storage recording technologies, and random access multi-state memories. According to their potential and expected impact, it is estimated that multiferroic technologies could soon reach multibillion US dollar market value.

“…The gyrator was invented by Tellegen (1948). Zhai et al (2009) developed three trilayer gyrators structures based on Terfenol-D/PZT/Terfenol-D, Nickel/PZT/Nickel and Metglas/PZT/ Metglas operating at the electromechanical resonance frequency (f % 86, 64 and 15 kHz, respectively). These magnetoelectric gyrators can convert not only active and reactive impedances, but also current and voltage (Zhai et al, 2009).…”

“…The coefficient s, which has the dimension of a resistance, we call the gyration resistance; 1/s we call the gyration conductance." The gyrator is a nonreciprocal network element that is discussed in the electrical engineering literature [15,31], for more recent developments see, e.g., [50] and [71]. For dimensional reasons, the electromagnetic excitations (D a , H a ) are related to the currents and the field strengths (E a , B a ) to the voltages, that is,…”

Abstract. Relativity theory is useful for understanding the phenomenology of the magnetoelectric effect of the antiferromagnet chromium sesquioxide Cr2O3 in two respects: (i) One gets a clear idea about the physical dimensions of the electromagnetic quantities involved, in particular about the dimensions of the magnetoelectric moduli that we suggest to tabulate in future as dimensionless relative quantities; (ii) one can recognize and extract a temperature dependent, 4-dimensional pseudoscalar from the data of magnetoelectric experiments with Cr2O3. This pseudoscalar piece of Cr2O3 is odd under time reflections and parity transformations and is structurally related ("isomorphic") to the gyrator of electric network theory, the axion of particle physics, and the perfect electromagnetic conductor of electrical engineering.
