We present a neutron polarimetric experiment where two kinds of spinor precessions are observed: one is induced by different total energy of neutrons (zero-field precession) and the other is induced by a stationary guide field (Larmor precession). A characteristic of the former is the dependence of the energy-difference, which is in practice tuned by the frequency of the interacting oscillating...

In this paper we propose a new model for quasi-periodic oscillations (QPOs) based on oscillating magnetohydrodynamic modes in neutron star magnetospheres. We argue that the interaction of the accretion disk with the magnetosphere can excite resonant shear Alfvén waves in a region of enhanced density gradients, the region where accretion material flows along the magnetic field lines in the magne...

We study the nonlinear dynamics of single-domain ferromagnetic nanoparticles in a viscous liquid induced by harmonically oscillating gradient magnetic field absence and presence static uniform field. Under some physically reasonable assumptions, we derive coupled set stiff ordinary differential equations for magnetization angle particle coordinate describing rotational translational motions nan...

We demonstrate an alternative nuclear spin resonance using a radio frequency (rf) electric field [nuclear electric resonance (NER)] instead of a magnetic field. The NER is based on the electronic control of electron spins forming a domain structure. The rf electric field applied to a gate excites spatial oscillations of the domain walls and thus temporal oscillations of the hyperfine field to n...

Abstract. In this work, it is experimentally shown that the weak oscillating magnetic field (known as “radiation damping” field) caused by inductive coupling between transverse magnetization of nuclei and radio frequency circuit perturbs remote resonances when homonuclear total correlation mixing applied. Numerical simulations are used to rationalize effect.

An analysis of an oscillatory magnetohydrodynamic (MHD) convective flow of anOldroyd-B, incompressible and electrically conducting fluid through a porous medium bounded within two infinite vertical parallel porous plates is carried out. The fluid is injected with constant velocity through the stationary porous plate and simultaneously sucked with same constant velocity through the other oscilla...

Dynamic phase transition in diluted kinetic Ising model in two dimensions has been studied in presence of external time dependent oscillating magnetic field applying Glauber Monte Carlo spin flip dynamics. A dynamic phase transition from a dynamically ordered to dynamically disordered ferromagnet is identified studying dynamic order parameter against temperature for different concentrations of ...

Nonlinear evolution of magneto-hydro-dynamic (MHD) oscillatory phenomenon driven by the interaction with energetic particles has been studied in CHS using twin heavy ion beam probes. The measurements have provided the fine observation of internal structure of plasma quantities, such as electric field, density and magnetic field distortion during a cycle of the MHD phenomenon. The finding of a n...
