Abstract
Currently there are many types of sensors that are used
in lots of applications. Among these, magnetic sensors are a good alternative for the detection and measurement of
different phenomena because they are a “simple” and readily available technology. For the construction of such devices
there are many magnetic materials available, although amorphous ferromagnetic materials are the most suitable.
The existence in the market of these materials allows the
production of different kinds of sensors, without requiring expensive manufacture investments for the magnetic cores.
Furthermore, these are not fragile materials that require
special care, favouring the construction of solid and reliable devices. Another important feature is that these sensors can be developed without electric contact between
the measuring device and the sensor, making them especially fit for use in harsh environments. In this review we will look at the main types of developed magnetic sensors. This work presents the state of the art of magnetic sensors based on amorphous ferromagnetic materials used in modern
technology: security devices, weapon detection, magnetic maps, car industry, credit cards, etc.
