Abstract

Heterostructures of NiFe/NiO/[Co/Pt] with mutually orthogonal easy axes allow for isothermal tuning of the magnetic coercivity at room temperature with no associated shift in the hysteresis loop along the applied field axis. This is in contrast to what is typically seen in exchange biased heterostructures. The NiFe coercivity is enhanced from 14.5 to 105Oe through the application of moderate dc magnetic fields of
