- Abstract
- We have studied the magnetic properties of a 240 degrees C ion implanted MnGe alloy (100 keV, 2 x 10(16) ion/cm(2)) by means of magneto-optical Kerr effect (MOKE) hysteresis loops taken at different wavelengths in the visible/near-infrared range and at different temperatures (12-180 K). The details of the MOKE response indicates that the magnetic properties of the sample are due to the contribution of multiple magnetic phases. These can be ascribed to the known coexistence of Mn atoms diluted in the monocrystalline Ge matrix and of amorphous semiconductive Mn-rich precipitates embedded in it. Our results demonstrate that both phases contribute to the ferromagnetic ordering in MnxGe1-x magnetic semiconductors. (literal)
