We compare the direct and inverse techniques of measuring magnetostriction in magnetic thin films. We chose a set of four magnetic thin film samples (Co95Fe5, Co60Fe20B20, Ni65Fe15Co20, and Ni80Fe20) for the measurements, representing positive and negative magnetostriction and having saturation magnetostriction of magnitudes ranging from 10-7to 10-5. We made the direct measurements on a high-precision optical cantilever beam system, and we carried out the inverse magnetostriction measurements on a nondestructive inductiveB-Hlooper with three-point bending stage.
