The described method for the anisotropy field measurement uses two fields HLand HT. The deviation of magnetization from the easy direction, and hence also sense signals, are proportional to these fields. The ratio of two integrated sense signals at H_{L} = 0 and H_{L} \neq 0 reaches a certain value (∼ 2.5) with field H_{T} = H_{k} . In this way, Hkmay be measured by a device designed for the coercive force measurement.
