magnetometers are also discussed.

This collection of seven chapters timely written by leading researchers and academics provide a comprehensive overview of the sensing fundamentals, principles, thermodynamic and phononic properties and recent developments in the applications of magnetic sensors in various fields such as local positioning, attitude control of micro-satellites, field sensors and biomedicine. An indispensable reference for budding researchers in this exciting field and application engineers from the industrial community, this compilation will bring the readers up to speed with the latest advances in the domain of magnetic sensing and their wide range of potential

Chapter 1 provides an overview of the recent developments in the study of the thermodynamic and phononic properties of pure and doped perovskite manganites, outlining therein important information about their cohesive, thermal, elastic, phonon and vibrational properties. The author has also provided a comprehensive treatment of the background and theoretical basis associated with the study of specific physical properties in these materials. Using a recently developed Extended Rigid Ion Model, the author also outlined its usefulness in the providing a theoretical framework to explain the physical properties observed in these advanced materials. A separate work focusing on modeling of induction sensors is given in Chapter 2. Here, the authors highlight their method to model the induction sensor and how the information can be used to other types of sensors. An analytical model was summarized and methods to improve the sensing performation of the induction

With the improvement in production techniques in microwires, orthogonal fluxgates as magnetic sensors are fast regaining prominence as the demand for small size sensors in modern applications are increasing at tremendous rates. Chapter 3 provides a comprehensive review of recent advancements in the area of orthogonal fluxgates. Methods of improving the various performance parameters such as sensitivity, linearity, noise of the sensor and physical structure of the orthogonal fluxgates are extensively presented in this chapter. Micro fluxgate sensors are given attention in Chapter 4 which outlines the use of microelectromechanical system (MEMS) manufacturing technology to fabricate this class of magnetic sensors. In addition, the chapter also described current research status in resonant sensors and Hall Sensors
