The magnetic properties of the Co 2 MnSi film under different piezo-voltages. (a) The piezo-voltage dependence of the saturation field in the [1À10] and [110] directions; the voltage step is 10 V. (b) The magnetic hysteresis loops maintain the hard axis in the [100] direction under different piezo-voltages. The inset is the definition of the q and a. q(a) is the angle between the magnetization (magnetic field) and [1À10] direction.

... Fig. 4c). Under the negative piezo-voltages, the loops of the [1À10] direction keep the square curve stabilized (as shown in Fig. 4d). We also measured the magnetic hysteresis loops of the [100] hard magnetic axis and the loops maintained the hard magnetic properties with the positive or negative piezo-voltages (only a part of the loops shown in Fig. 5b). Through the magnetic measurement along different directions, we summarized the variation of the saturated eld with the piezo-voltage in Fig. 5a. The saturated elds of [110] and [1À10] directions show opposite trends with the piezo-voltages. When the piezo-voltage increases to 40 V, the [1À10] direction has a large saturated eld ...

The saturated elds of [110] and [1À10] directions show opposite trends with the piezo-voltages. When the piezo-voltage increases to 40 V, the [1À10] direction has a large saturated eld and shows a two-step loop.

... K U and K C are the effective uniaxial and cubic anisotropy constants respectively, H is the applied external magnetic eld, M S is the saturation magnetization, q is the angle between the magnetization and the easiest axis [1À10], and a is the angle between the external magnetic eld and the easiest axis [1À10] (see the inset of Fig. 5b). With the saturation eld and slope of the two-step loops, the K U and K C can be calculated ...
