The vertical correlation of magnetic domains in a Co/Cr/Co trilayer is statistically quantified as a function of an applied magnetic field. These measurements, used with determinations of the individual layer magnetometry curves, identify the presence of both antiferromagnetic exchange coupling and ferromagnetic dipolar coupling for different regions within the trilayer.
