摘要:

近年来,一些非磁性材料由于表面和尺寸效应而在纳米尺度上表现出磁性行为。对这些效应的实验观察是基于对非常小的磁信号的测量。因此,当测量小信号(通常低于0.0001 emu)时,一些对于具有大磁信号的散装材料不重要的杂散效应可能变得重要。在这里,我们总结了这些小磁信号的一些来源,在研究这种新的纳米磁性时应该考虑这些来源

英文摘要:

It has been recently reported that some non-magnetic materials in bulk state, exhibit magnetic behavior at the nanscale due to surface and size effects. The experimental observation of these effects is based on the measurement of very small magnetic signals. Thus, some spurious effects that are not critical for bulk materials with large magnetic signals may become important when measuring small signals (typically below 0.0001 emu). Here, we summarize some sources of these small magnetic signals that should be considered when studying this new nanomagnetism
