摘要：

We present the first magnetization measurements of single submicronic particles at very low temperature made of either Ni, Co, CoZrMoNi or TbFe. As detector we use a micro-bridge de-SQUID deposited onto or next to the sample. Sample and detector are patterned by electron-beam lithography. The dynamics and the temperature dependence of the magnetization reversal is studied in view of Macroscopic Quantum Tunneling (MQT).
