Anisotropic Exchange in
We investigate the magnetic properties of the multiferroic quantum-spin
system LiCuO by electron spin resonance (ESR) measurements at - and
-band frequencies in a wide temperature range \,K). The observed anisotropies of the tensor and the ESR linewidth in
untwinned single crystals result from the crystal-electric field and from local
exchange geometries acting on the magnetic Cu ions in the zigzag-ladder
like structure of LiCuO. Supported by a microscopic analysis of the
exchange paths involved, we show that both the symmetric anisotropic exchange
interaction and the antisymmetric Dzyaloshinskii-Moriya interaction provide the
dominant spin-spin relaxation channels in this material.Comment: 10 pages, 10 Figure
IDIOPATHIC NORMAL PRESSURE HYDROCEPHALUS (HAKIM-ADAMS SYNDROME): CLINICAL SYMPTOMS, DIAGNOSIS AND TREATMENT
Idiopathic normal pressure hydrocephalus is a chronic steadily progressing disease. Nowadays a vital and acute socially
significant problem still has not been solved. The etiology and pathogenesis of this disease remain so far poorly understood. Variable
clinical manifestations, as well as difficulties in differential diagnosis with other neurodegenerative diseases - lead to unde r-
diagnosing of the illness that causes a significant decrease in patient’s quality of life and even results in disability. The n umber of
patients with idiopathic normal pressure hydrocephalus has been steadily increasing. That is why, the coverage and a full study of
this problem is of great interest for a broad circle of medical professionals
