Studies of eta-mesic nuclei at the LPI electron synchrotron
V. A. Baskov, A. V. Koltsov, A. I. L'vov +10
A brief review of searches for eta-mesic nuclei is presented with emphasis on photoreactions and results of a new experiment done at the LPI electron synchrotron are reported. Deca…
Using metallic photonic crystals as visible light sources
Sergei Belousov, Maria Bogdanova, Alexei Deinega +8
In this paper we study numerically and experimentally the possibility of using metallic photonic crystals (PCs) of different geometries (log-piles, direct and inverse opals) as vis…
Field-induced Polar Order at the Néel Temperature of Chromium in Rare-earth Orthochromites: Interplay of Rare-earth and Cr Magnetism
B. Rajeswaran, D. I. Khomskii, A. K. Zvezdin +2
We report field-induced switchable polarization (P = 0.2 ~ 0.8 microC/cm2) below the Néel temperature of chromium (TN Cr) in weakly ferromagnetic rareearth orthochromites, RCrO3 (R…
Electron shell and the alpha-decay
Sergey Yu. Igashov, Yury M. Tchuvil'sky
The ratio of the alpha-decay widths of a bare nucleus and the related atom is calculated. Both the change of the form and thus the penetrability of the potential barrier and the ef…
Magnetocaloric properties of La0.7Ca0.3Mn16O3 and La0.7Ca0.3Mn18O3 manganites and their sandwich
A. M. Aliev, A. G. Gamzatov, K. I. Kamilov +2
It is shown that the use of sandwich from materials with near similar magnetocaloric properties increases the relative cooling power by about 20 %.
Nonlinear magnetic response of the magnetized vacuum to applied electric field
Dmitry M. Gitman, Anatoly E. Shabad
We find first nonlinear correction to the field, produced by a static charge at rest in a background constant magnetic field. It is quadratic in the charge and purely magnetic. The…
