Quantum oscillations in a molecular magnet [PDF]
Nature, 2008 The term 'molecular magnet' generally refers to a molecular entity containing several magnetic ions whose coupled spins generate a collective spin, S (ref. 1). Such complex multi-spin systems provide attractive targets for the study of quantum effects at the mesoscopic scale.

Magnetic breakdown spectrum of a Kramers–Weyl semimetal
New Journal of Physics, 2020 We calculate the Landau levels of a Kramers–Weyl semimetal thin slab in a perpendicular magnetic field B . The coupling of Fermi arcs on opposite surfaces broadens the Landau levels with a band width that oscillates periodically in 1/ B .

Neural oscillators for magnetic hysteresis modeling
CoRR, 2023 Hysteresis is a ubiquitous phenomenon in science and engineering; its modeling and identification are crucial for understanding and optimizing the behavior of various systems. We develop an ordinary differential equation-based recurrent neural network (RNN) approach to model and quantify the hysteresis, which manifests itself in sequentiality and ...

Spatial antiferromagnetic spin texture as a nano-oscillator
Scientific Reports, 2023 We report a theoretical study of the localized spatial magnetization configuration, which is a confined spin configuration of the target skyrmion/hopfion type in an antiferromagnet with perpendicular magnetic anisotropy, and then we solve the particular ...

Detection of fast oscillating magnetic fields using dynamic multiple TR imaging and Fourier analysis. [PDF]
PLoS ONE, 2018 Neuronal oscillations produce oscillating magnetic fields. There have been trials to detect neuronal oscillations using MRI, but the detectability in in vivo is still in debate. Major obstacles to detecting neuronal oscillations are (i) weak amplitudes, (

Modulating the magnetosphere of magnetars by internal magneto-elastic oscillations [PDF]
, 2014 We couple internal torsional, magneto-elastic oscillations of highly magnetized neutron stars (magnetars) to their magnetospheres. The corresponding axisymmetric perturbations of the external magnetic field configuration evolve as a sequence of linear ...

Magnetic Oscillations in the Nambu - Jona-Lasinio model [PDF]
, 1999 The phase structure of a simple Nambu-Jona-Lasinio model has been investigated at non-zero values of $\mu$ and H, where H is an external magnetic field and $\mu$ is the chemical potential. On this basis magnetic oscillations effects were considered.

Determination of the coronal magnetic field by coronal loop oscillations [PDF]
, 2001 We develop a new method for the determination of the absolute value of the magnetic field strength in coronal closed magnetic structures, based on the analysis of flare-generated oscillations of coronal loops.

Magnetic microchains and microswimmers in an oscillating magnetic field [PDF]
Biomicrofluidics, 2016 Superparamagnetic micro-bead chains and microswimmers under the influence of an oscillating magnetic field are studied experimentally and numerically. The numerical scheme composed of the lattice Boltzmann method, immersed boundary method, and discrete particle method based on the simplified Stokesian dynamics is applied to thoroughly understand the ...
