ball-milling increases Co/Si interfaces and, hence, the GMR ratio. The effect of Co/Si interfaces on GMR was further examined in the thin film structure [21]. Compared with all metallic alloys [17-19], the MR ratio from the GMR effect in these ball-millled ferromagnetic-semiconductor powders is lower because the Si matrix is more electrically resistive and the milling time is relatively

The ball-filling rate (Fr), the mill speed (Nr), and the ball size (Db) are considered to study this phenomenon. The simulations results show by a time series representation, fast Fourier transform, and short-time Fourier transform (STFT), that the acceleration is significantly affected by the presence of the grinding forces, developing an impulsive noise due to the impact of the

Ball milling procedures are often referred to as ''milling at room temperature'' [9, 10]. This term should be used carefully, as even within short milling times a temperature increase can be observed, if there are no precautions for temperature control. For example, it was shown that mil- ling in a mixer ball mill (MBM) for 10 min with two milling balls in a 10 ml beaker raised the
