Magnetic polymer composites filled with microparticles of the nanocrystalline 5BDSR alloy have been studied. Measurements have been performed mainly by the ferromagnetic resonance method complemented by other spectroscopic ...

The technique of calculation of the n-phonon transition rates between electronic sublevels of impurity rare earth ions in dielectric crystals is developed in the case when n>2. The n-phonon transition probabilities are ...

The EPR spectra of Ce3+ impurity ions in LiYF4, LiLuF4, and LiTmF4 double-fluoride single crystals have been investigated at a frequency of ~9.3 GHz in the temperature range 5-25 K. The effective g factors of the ground ...

In BaF2 crystals doped with paramagnetic Yb3+ ions, at concentrations higher than 0.01 at %, an EPR line was observed corresponding to a linear cluster Yb-F-Yb-F oriented along a threefold axis. © 2009 Pleiades Publishing, Ltd.

The electron paramagnetic resonance (EPR) spectra of Ce3+ and Nd3+ impurity ions in unoriented powders of the YBa 2Cu3O6.13 compound are observed and interpreted for the first time. It is demonstrated that, upon long-term ...

During crystallization, the LiF-YF3-LuF3 compounds form a continuous series of solid solutions having a scheelite structure at any proportion of the YF3 and LuF3 components. It is established that the crystals conform to ...
