Abstract:
An integrated Hall effect device for determining vector components of an external magnetic field, said device comprising:a conductive substrate having a top surface with a first section and a second section for carrying an electrical current, said first section being positioned proximate to said second section such that a first electrical signal is generated in response to one of the vector components of the external magnetic field acting perpendicularly on an electrical current in said conductive substrate; a ferromagnetic film having at least two configurable magnetization orientation states, and being disposed over a portion of said second section such that a fringe magnetic field generated by vector components of the external magnetic field acting on the magnetization of said ferromagnetic film projects from an edge of said ferromagnetic film that is over a portion of said second section, and such that a second electrical signal is generated in response to the fringe magnetic field acting on an electrical current in said conductive substrate; and a detector for detecting the presence of said first and said second electrical signals.
