چکیده
Recent progress in the development of high-frequency (HF) magnetic materials and devices requires HF imaging field response with high spatial resolution. In this work, we proposed Alternating Magnetic Force Microscopy (A-MFM) a superparamagnetic tip to image energy near sample surface. frequency from 100 kHz 1 GHz was emanated by writing head used for perpendicular recording. Applied is amplitude modulated, determines modulation cantilever oscillation framework A-MFM. The modulated caused low alternating force, which generated interaction between AC tip.

We present quantitative, high spatially resolved magnetic force microscopy imaging of samples based on 11 nm diameter superparamagnetic iron oxide nanoparticles in air at room temperature. By a proper combination of the cantilever resonance frequency shift, oscillation amplitude and phase lag we obtain the tip-sample interaction maps in terms of force gradient and energy dissipation. These phys...
متن کاملHeating magnetic fluid with alternating magnetic field
This study develops analytical relationships and computations of power dissipation in magnetic fluid (ferrofluid) subjected to alternating magnetic field. The dissipation results from the orientational relaxation of particles having thermal fluctuations in a viscous medium. r 2002 Elsevier Science B.V. All rights reserved.
