Fig. 9

CoMφ mapping of the Cu thin film after cycling between 100 and 400 °C, with 20 ms pulse length for 1 cycle (a), 500 cycles (b), and 1000 cycles (c). The histogram in (d) shows the initial CoMφ mean value around 4.6°. Cycling shifted towards 3.7° after 500 pulses before parts of the grain started turning out of the scanned range of φ.
