A method is provided for determining at least one material characteristic of a magnetizable metal body by means of a micromagnetic sensor arrangement, which comprises at least one excitation coil having a magnetic core for signal excitation and at least one receiver. The body is magnetized by the sensor arrangement via current or voltage excitation of the sensor arrangement, which comprises at least one sign change between a positive part of a half-wave and a negative part of a half-wave. At least one signal is measured in the receiver, and the signal is Fourier transformed. The material characteristic are determined from at least one Fourier component. The excitation is turned off, and the post-oscillation of the signal is measured in the receiver. At least the part of the signal resulting from the post-oscillation in the Fourier transformation is used.
