[求助] 关于磁性问题的请教,急!!! 已有2人参与

小弟对磁性不是很懂,不太明白审稿人的意思,不知该如何回答,还请懂这方面的牛人帮帮忙。下面是审稿人的意见:
5) Magnetic measurements: in line 216 it is written “remanence and coercivity are zero”. Is it Mr=0 emu/g and Hc=0Oe or this values are close to zero like Mr a few emu/g and Hc= over a dozen Oe, what is common for nanosized soft magnetic spinel ferrites? This needs clarification

这是我文中的图,我就是顺便做了这个测试,怎么看剩磁和矫顽力是不是零啊?关键现在不知怎么回答审稿人啊?

我觉得就是需要表征材料的矫顽力和剩磁,而且要说明这是软磁尖晶石铁氧体。

For soft magnetic spinel ferrites, the remanence and coercivity are strongly dependent on the particle size. For a multi domain sample, the coercivity may changes from several tens Oe to hundred Oe, and the  remanence is dependent on the sample weight (it should not be zero any way).  If your sample is in single domain state, then it is superparamagnetic and the coercivity  and  remanence should be zero.

You can distinguish superparamagnetic from ferri/ferromagnetic state by the particle size, or by carry out ZFC-FC measurement.
