Ecofriendly hydrothermal reduction of graphene oxide is widely used for producing hydrogels and aerogels, but it yields partly reduced graphene oxide (prGO) containing oxygen groups and some number...

Partially reduced graphene oxide (prGO) obtained by hydrothermal reduction was studied by electron paramagnetic resonance (EPR) spectroscopy in the temperature range 4.2–300 K. The EPR absorption is accompanied by nonresonant microwave absorption d

Paramagnetic centers in graphene oxide (GO) were studied by continuous wave and pulsed electron paramagnetic resonance (EPR) in the temperature range 4.2–300 K. Saturation of the EPR signal indicates long spin relaxation times of the paramagnetic c

We study the coherent dynamics of a qubit excited by an amplitude-modulated electromagnetic field under the Rabi resonance when the frequency of the low-frequency modulation field matches the Rabi frequency in the high-frequency field. Due to destruc

Using SQUID magnetometry and ferromagnetic resonance we show that the intrinsic ferromagnetism in graphene oxide (GO) is related to the zigzag edges created by breaking GO layers in the process of exfoliation. The 1D magnetic order existing below 2 K

The decay of Rabi oscillations provides direct information about coherence of electron spins. When observed in EPR experiments, it is often shortened by spatial inhomogeneity of the microwave field amplitude in a bulk sample. In order to suppress thi

Observation of Griffiths Phase in Oxygen-Deficient La0.70Sr0.30MnO3−γ by Electron Magnetic Resonance

Journal of Applied Spectroscopy. 84:683-686
The oxygen-deficient polycrystalline La0.70Sr0.30MnO3−γ (0 < γ ≤ 0.2) manganites were studied by electron magnetic resonance (EMR). The EMR spectra provide evidence for an unusual and γ-dependent transition of manganites from the ferromagnetic

Effect of Rabi splitting on the low-temperature electron paramagnetic resonance signal of anthracite
Publikováno v:
Journal of Magnetic Resonance. 274:73-79
Specific distortions of the EPR signal of bulk anthracite are observed at low temperatures. They are accompanied by variations in the microwave oscillator frequency and are explained by the manifestation of the Rabi splitting due to the strong coupli

We study Rabi oscillations of the second-order Raman transition realized on dressed states of a qubit excited by an amplitude-modulated microwave field. The co-rotating component of the ultrastrong low-frequency modulation field excites virtual multi
