Superconducting Quantum Interference

One of the new materials that have recently attracted wide attention of researchers are magnetoelectric (ME) composites. Great interest in these materials is due to their properties associated with the transformation of electric polarization/magnetization under the influence of external magnetic/electric fields and the possibility of their use to create new devices. In the proposed review, ME magnetic field sensors based on the widely used structures Terfenol—PZT/PMN-PT, Metglas—PZT/PMN-PT, and Metglas—Lithium niobate, among others, are considered as the first applications of the ME effect in technology. Estimates of the parameters of ME sensors are given, and comparative characteristics of magnetic field sensors are presented. Taking into account the high sensitivity of ME magnetic field sensors, comparable to superconducting quantum interference devices (SQUIDs), we discuss the areas of their application.

Optical Phenomenon

An innovative temperature sensor has been presented based on “Faraday Effect”. The Faraday Effect or the Faraday rotation is a magneto-optical phenomenon; that is, an interaction between electromagnetic wave and a magnetic field in a medium. Optical sensors based on the Faraday Effect have the advantages of simplicity, high electrical insulation and immunity to electromagnetic interference. We will be making use of an optical fiber and a permanent magnet as our sensing elements. The magnet will be the sensing element for change in temperature and the fiber optic cable will sense the change in magnetic field intensity corresponding to the change in temperature.
