Orientations of the samples (gray) and the coordinate systems. Subscripts stand for “sample holder” and for “sample” . The axes of the sample coordinate system are parallel to the edges of the sample while the axes of the sample holder are parallel to the bottom and back surface of the sample holder. The magnetic field, , is rotating in the plane around the axis.
Strain vs the number of magnetomechanical cycles of both samples. The dashed line indicates the cycle number at which the mounting conditions of sample A and B were inspected.
Magnetic-field-induced strain vs the direction of the magnetic field for selected cycles of samples A and B. Both examples are measured in the second orientation with at 45° to the sample holder: for sample A at 10 000 MMCs (after inspection) and for sample B at 100 MMCs (before inspection).
Strain vs the number of magnetomechanical cycles (logarithmic scale) of all experiments of sample A. The full and open squares are identical to Fig. 2 and indicate the first and second 45° orientation shown in Fig. 1. The full triangles pointing to the right and up indicate test with the sample’s axis in horizontal and vertical direction, respectively. The open triangles pointing to the right, are results of the sample mounted with the axis being horizontal, after a thermomechanical training in -direction. The half-open square shows the strain with the sample mounted in the second orientation with at 45° to the sample holder.
