ScanSens presents the new developement: 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 recognize sectors of different functionality of the hard disk investigated (which are mentioned on scans’ captures).
To the left - AC-MFM image of servo sector. Scan size: 10×10 μm2 (with 5 nm step), section size: 2,5 μm.
To the right - AC-MFM image of user data sector. Scan size: 8×8 μm2 (with 5 nm step), section size: 2,5 μm (section of AGC preamble area) .
| 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.

How to get amount discount:
1. Add a box with 50 probes* to the Shopping Cart.
2. Change in the Shopping Cart the box quantity to the one you need.
3. Click the button 'Reculculate!' and get your discount.
* You can choose boxes with 50 probes of different ETALON series.
For example - for the order:
HA_FM/50 - 1 box
HA_NC/50 - 2 boxes
HA_HR/Pt/50 - 1 box
amount discount will be 25%, since 4 boxes with 50 chips are ordered.
** - for USA market there is another discount system. Please, contact us for further information.
