Methodology of magnetorheological sport damper demagnetization
, 2015 This thesis is dedicated to discovering the most efficient methods of demagnetization. At the beginning, basics of magnetorheological (MR) dampers are explained. Available literature is studied to propose appropriate methods of demagnetization.

Ab Initio Nonadiabatic Molecular Dynamics of Ultrafast Demagnetization in Iron
Ultrafast demagnetization in magnetic metals is the key to spintronics devices. Taking iron as a prototypical system, we investigate the demagnetization mechanism by simulating the charge and spin dynamics using nonadiabatic molecular dynamics in the ...

Chemistry – A European Journal, EarlyView.This study introduces PROSPECT, a 2D solid‐state NMR method that correlates MHz‐wide, low‐γ anisotropic powder patterns. PROSPECT operates by progressively depleting a shared 1H dipolar‐order reservoir via two independently stepped cross‐polarizing offsets, yielding homonuclear and heteronuclear correlations without requiring direct transfers or even ...

The demagnetization field of multidomain grains.
Journal of geomagnetism and geoelectricity, 1977 The demagnetization ‘constant’, N, enters into all theoretical considerations of multidomain remanence. Although most workers believe N to be related simply to the shape of the grain, no theoretical study of N has previously been completed. It is shown in this paper thatN monotonically increases with increase in remanence in multidomain grains ...

Chemistry – A European Journal, EarlyView.The use of 2‐aminoisobutyric acid in 3d–4f chemistry affords three {Ni₉Ln5} clusters, with the Gd analogue exhibiting an unusually broad magnetocaloric effect across an extended temperature range. ABSTRACT The solvothermal reaction between Ni(HCOO)2.2H2O, 2‐aminoisobutyric acid (aibH), Ln(OAc)3·4H2O (Ln = Gd, Y, Dy) and NEt3 in MeOH/MeCN affords the ...

Ultrafast Transitions in X‐Ray Irradiated Solids
Contributions to Plasma Physics, EarlyView.ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Ultrafast demagnetization dynamics of 4f antiferromagnets [PDF]
We study the ultrafast demagnetization dynamics of LnRh2Si2 (Ln = Pr, Nd, Sm, Gd, Tb, Dy, Ho) antiferromagnets after excitation by a laser pulse, using a combination of density functional theory and atomistic spin and spin-lattice dynamics simulations ...

Demagnetization factor for a powder of randomly packed spherical particles [PDF]
, 2013 The demagnetization factors for randomly packed spherical particle powders with different porosities, sample aspect ratios, and monodisperse, normal, and log-normal particle size distributions have been calculated using a numerical model.

InfoScience, EarlyView.An excellent comprehensive performance bidisperse magnetorheological fluid (MRFs) was developed by blending self‐synthesized micron‐sized flaky FeSiCr particles with CIPs. Through the synergistic modification of particle properties, morphology and composition, this approach overcomes the challenges of achieving an optimal balance among key performance ...
