Technology for fabrication of a micromagnet on a tip of a MFM/MRFM probe

A method for coating the tip of a mechanical resonator for use in magnetic force microscopy and magnetic resonance force microscopy in which the tip is coated with a ferromagnetic material and the cantilever is not, and the product resulting from the method. A cantilever and incorporated tip are coa...

Beschreibung
Zusammenfassung:	A method for coating the tip of a mechanical resonator for use in magnetic force microscopy and magnetic resonance force microscopy in which the tip is coated with a ferromagnetic material and the cantilever is not, and the product resulting from the method. A cantilever and incorporated tip are coated with a photoresist, except that surface tension keeps photoresist off the tip. The cantilever and tip are then coated with a magnetic material. Next, acetone is used to lift off the magnetic material from the cantilever but not from the tip.
