The years between Hungary’s occupation by the Red Army that concluded its traumatic involvement in the Second World War and the construction of socialist dictatorship in the country at the end of the 1940s constitute a moment of transition, a moment that is central to understanding the subsequent development of the country. For this reason the interpretation of this moment of transition has bee...

We have investigated the individual magnetic moments of Ni, Mn and Tb atoms in the intermetallic compound TbNi2Mn in the Laves phase (magnetic phase transition temperature TC ∼131 K) by X-ray magnetic circular dichroism (XMCD) studies at 300 K, 80 K and 20 K. Analyses of the experimental results reveal that Ni atoms at 20 K in an applied magnetic field of 1 T carry an intrinsic magnetic moment ...

We examine the Ising chain in a transverse field at zero temperature from the point of view of a family of moment formalisms based upon the cumulant generating function, where we find exact solutions for the generating functions and cumulants at arbitrary couplings and hence for both the ordered and disordered phases of the model. In a t-expansion analysis, the exact Horn-Weinstein function E(t...

tow new compound of type [(chelate)2cu-oh-cu(chelate)2] x3.nh2o, where chelate=1,10-phenanthroline; x=cl¯(n=3.5) and chelate=4,4'-dimethyl-2,2'-bipyridine;  (n=5) have been synthesized and their properties investigated. the complexes show room temperature magnetic moment order of 1.0 b.m. per copper atom. the x-band esr spectrum of powdered samples at room temperature shows typical dm=1 transit...

Stark spectroscopy has been applied to a wide range of molecular systems and materials. A generally useful method for obtaining electronic and vibrational Stark spectra that does not require sophisticated equipment is described. By working with frozen glasses it is possible to study nearly any molecular system, including ions and proteins. Quantitative analysis of the spectra provides informati...
