High-speed magnetization switching of a nanomagnet is necessary for faster information processing. The ballistic switching by a pulsed magnetic filed is a promising candidate for the high-speed switching. It is known that the switching speed of the b

Recent advances in experimental techniques have made it possible to manipulate and measure the magnetization dynamics on the femtosecond time scale which is the same order as the correlation time of the bath degrees of freedom. In the equations of mo

The analysis of a second-order pattern on a proton NMR spectrum is proposed using a multi field NMR measurement, a spectral simulation, a DFT calculation and a solvent effect study. The ordinary 9.4 T proton NMR measurement of 1,3-dichloro-2-nitroben

The keto-enol tautomerism of phenylpyruvic acid (PPA) has been studied by temperature-variable 9.4 T nuclear magnetic resonance (NMR) spectroscopy. It was found that PPA favored its existence in the enol form in dimethyl sulfoxide (DMSO) solvent, 93.

The magnetization switching in a perpendicularly magnetized nanomagnet by applying a circularly polarized rf field is analyzed as a function of the thickness (d) of the specimen using an effective one-dimensional model. It is found that there exist t

We propose a novel formation model of an intermolecular hydrogen bond between radicals and a diamagnetic matrix in the condensed phase. W-band and multi-frequency ESR studies revealed that the poly...

Multifrequency (X-, Q-, and W-band) electron spin resonance (ESR) spectroscopy has been used to characterize the phenoxyl radical produced from alpha-(3,5-di-tert-butyl-4-hydroxyphenyl)-N-tert-butylnitrone, which is a new spin-trapping reagent. The X

We systematically investigated the spin wave-assisted magnetization switching (SWAS) of a L10-FePt / Ni81Fe19 (Permalloy; Py) exchange-coupled bilayer using a pulse-like rf field (hrf) and mapped the switching events in the magnetic field (H) - hrf f
