High resolution long lifetime magnetic probes MFM01 series

 

The choice of the proper probe is very important during magnetic measurements. The magnetic probe should provide high resolution images with good magnetic signal. Besides it should “survive” under high-humidity conditions.
NT-MDT offers new development – high resolution long lifetime magnetic probes MFM01 and MFM10. Special protective layers help to avoid oxidation and increase the cantilever lifetime substantially. Sharp silicon tip with coating less than 40 nm allows obtaining magnetic resolution till 20-30 nm!
