Phys. Lett. 91, 123513 (2007); http://dx.doi.org/10.1063/1.27893910003-6951http://hdl.handle.net/10919/25173Here, the authors report a new type of geomagnetic field sensor based on the giant magnetoelectric effect in Metglas/piezoelectric-fiber laminates that are wrapped with a coil. These sensors can measure quite precisely the value of both the Earth's magnetic field and its inclination. The geomagnetic field sensor does not require a dc magnetic bias and is driven by a 10 mA ac. Highly sensitive dc magnetic field variations of less than 10(-9) T and angular inclinations of <= 10(-5) deg can be detected, potentially offering opportunities for a small global positioning device.
