It has been recently reported that some nonmagnetic materials in bulk state exhibit magnetic behavior at the nanoscale 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 10−4emu). Here, we summarize some sources of these small magnetic signals that should be considered when studying this new nanomagnetism.

Interface-Induced Phenomena in Magnetism (2016, unknown): “These situations push experimental methodologies used to understand the magnetism in these systems to their limits, particularly as the magnetism is often weak and derived from small volumes [Garcia et al., 2009].”
Magnetic Oxide Heterostructures (2014, background): “These magnetic probes are especially valuable as techniques complementary to conventional magnetometry methods, which can yield spurious results when applied to low-signal samples (145), such as a few magnetic unit cells at an interface.”
Production and processing of graphene and related materials (2020, methodology): “The samples were handled following basic precautions like using plastic tools, to avoid metallic contamination, [1374] flushing the fresh Si substrates with nitrogen, to remove dust, and depositing <4% of a monolayer of NPs to avoid NPs interactions [1375].”
