In Py/CrAl bilayers (where Py=Ni81Fe19), the coercivity at room temperature is found to be a linear function of 1/t3/2FM, indicating the existence of random exchange interaction at the FM/AFM interface (FM=ferromagnetic, AFM=antiferromagnetic). The AFM layer thickness dependencies of the He and Hc are also studied.
