Theory of magnetic force driven magnetoelectric effect in piezo-bimorph/ferrite cantilever composite

Quantum Dynamics of the Oscillating Cantilever-Driven Adiabatic Reversals in Magnetic Resonance Force Microscopy

We simulated the quantum dynamics for magnetic resonance force microscopy (MRFM) in the oscillating cantilever-driven adiabatic reversals (OSCAR) technique. We estimated the frequency shift of the cantilever vibrations and demonstrated that this shift causes the formation of a Schrödinger cat state which has some similarities and differences from the conventional MRFM technique which uses cycli...

The Effect of Substrate Clamping on Laminated Magnetoelectric Composite

A theory model was established to calculate the magnetoelectric voltage coefficient of piezoelectric/piezomagnetic laminated composites on silicon or magnesium oxide substrates. The magnetoelectric voltage coefficient is calculated as function of interface coupling factor k, volume ratio of piezoelectrics to piezomagnetic, and volume ratio of substrates to composite. It was found that the magne...

Magnetoelectric Ponderomotive Force

The dynamics of a system consisting of a matter continuum with a weak linear magnetoelectric coupling interacting with electromagnetic fields is examined on a local scale in a nonrelativistic limit. A consistent expression for the internal energy of the system is derived. The internal energy density and the continuity equation for the momentum lead to the derivation of ponderomotive forces. A n...

Magnetic Resonance Force Microscopy Cantilever Detection by Quantum Tunneling

Magnetic resonance force microscopy (MRFM) is a novel ultra-sensitive magnetic resonance detection scheme. In this scheme, forces are measured between a magnet-tipped cantilever and on-resonance spins. It has been proposed that this technique could be used to image biomolecules [1]. In order to increase the sensitivity of MRFM, it may become necessary to use radio-frequency (RF), rather than au...
