The MFM-image, received using magnetic cantilever

The sample is a recording magnetic tape.
Phase ../images are corresponded to magnetic image of the sample. One of them was recorded over 50 nm from the sample surface (one can find more features), other - over 100 nm.
Before working with magnetic mode you need to magnetized the tip (just put it on the current magnet) during 1-2 hours.

The price of magnetic cantilevers is 30$ per one cantilever, plus shipment and customs taxies.
