Description
ScanSens presents the new development: MFM cantilevers with CoFe magnetic coating. Sharp tip with magnetic layer’s thickness less than 20 nm allows to get magnetic contrast with down to 20-30 nm resolution!
To demonstrate excellent characteristics of CoFe cantilevers, amplitude-modulation magnetic force microscopy (AC-MFM) measurements of a modern high-density HDD were performed recently by an application engineer of our partners, NT-MDT Spectrum Instruments. Below the one may find scans obtained and their cross sections.
It is noteworthy that such detailed images allowed our engineers to recognise sectors of different functionality of the hard disk investigated (which are mentioned on scans’ captures).
NanoTechnology Solutions is the exclusive distributor of these products in Australia and New Zealand.
| Cantilever type | A | B | Typical dispersion |
| Length, L (µm) | 223 | 183 | ± 2 |
| Width, W (µm) | 34 | 34 | ± 3 |
| Thickness, H (µm) | 3 | 3 | ± 0.15 |
| Force Constant (N/m) | 3.5 | 6 | ±20% |
| Resonant frequency (kHz) | 77 | 114 | ± 10% |
*by the customer’s request cantilevers with different coating thickness could be manufactured. It will change their magnetic moment to fit to different experimental conditions and sample’s requirements.
