Claim:
1. A method of monitoring magnetoresistance, said method comprising; providing a junction device comprising a heterojunction composite comprising a p-type Group III-V ferromagnetic semiconductor component comprising a compound of a formula and an n-type Group III-V non-magnetic semiconductor component comprising a compound of a formula (M III M V ), wherein M III comprises a Group III metal component, M TM comprises a magnetic transition metal component and M V comprises a Group V metal component, and x is less than about 0.2; a diode coupled to said ferromagnetic semiconductor component and said non-magnetic semiconductor component of said heterojunction composite; and a voltage source for application of voltage across said device; applying a voltage across said device; applying a magnetic field oriented with respect to a current flow through said diode of said device, said magnetic field applied from about parallel to about perpendicular to direction of said current flow; and measuring magnetoresistance of said current responsive to said applied magnetic field.
