Abstract:
A method of orienting a magnetic film on a surface of a substrate comprising the steps of:orienting an electromagnet having first and second electromagnetic coils wrapped in different directions around a common core adjacent to the substrate's surface;directing a flow of electrical current through the first electromagnetic coil for producing a first uniaxial magnetic field along a first magnetic axis;directing a flow of electrical current through the second electromagnetic coil for producing a second uniaxial magnetic field along a second magnetic axis that extends in a direction different from the first magnetic axis; andregulating relative amounts of the electrical currents directed through the first and second electromagnetic coils for producing a compound uniaxial magnetic field that orients magnetic domains of the magnetic film along a compound magnetic axis that lies in a plane defined by the first and second magnetic axes.
