Mn containing alloy LMIS for Spintronics


Mn containing alloy LMIS for Spintronics

Akhmadaliev, C.; Pilz, W.; Bischoff, L.

Magnetic ions such as Mn are of increasing interest for the structuring of diluted magnetic semiconductors, e. g. spin-based optoelectronics in III-V as well as II-VI materials. Only a few Mn alloy liquid metal ion sources (LMIS) for nano-patterning are reported, so an Au-Si-Mn or an Au-Ge-Mn sources were used in mass separated FIB applications. The Mn-Ge alloy LMIS (melting temperature of 720°C) showed a stable operation at emission current of 2 - 30 µA. The slope of the I-V characteristic curve was ~0.11 µA/V at a heating current of about 2.6 A.
