An electronic device comprises first and second antennas for a first radio communication scheme that uses a diversity scheme, and a third antenna for a second radio communication scheme arranged between the first and second antennas. The system starts by loading a previously computed result for a function to a destination register for the function from a lookup table. The magnetic layer is also formed from grain boundary segregation materials comprising Manganese Oxide and at least one of Silicon Oxide, Chromium Oxide, and Cobalt Oxide.
