Dynamic magnetic behaviour of some diluted EuS and EuSe compounds
Autor: J C Verstelle, J. J. Baalbergen, A.J. Van Duyneveldt
Publikováno v: Physica B: Condensed Matter. 164:353-361
AC susceptibility measurements over a wide frequency range (1–10 8 Hz) on some Eu x Sr 1− x S ( x = 0.40 and 0.55) and Eu x Sr − x Se ( x = 0.50 and 0.70) compounds are reported. The analysis of the experimental data is concerned on the complex

Non-linear AC susceptibility of a spin glass Pd-5.5 at.% Mn
Autor: Bekir Özçelik, Kerim Kiymaç, A J van Duyneveldt, J. A. Mydosh, J C Verstelle
The authors have investigated the linear and the non-linear AC susceptibilities of a Pd-Mn spin glass with 5.5 at.% Mn around its transition temperature Tf, as a function of temperature, frequency and amplitude of the AC driving field. Through linear

LINEAR AND NONLINEAR AC SUSCEPTIBILITIES OF THE SPIN-GLASS EU0.4SR0.6S
Autor: J. A. Mydosh, Kerim Kiymaç, Bekir Özçelik, J C Verstelle, A J van Duyneveldt
WOS: A1992JG75000015 The linear and non-linear susceptibilities of a spin-glass Eu0.4Sr0.6S system have been measured in the temperature range from 1.2 to 4.2 K, for frequencies between 1 and 234 Hz. The freezing temperature T(f)(omega --> 0) of the

CONSEQUENCES OF COLE-COLE RELAXATION IN SPIN GLASSES
Autor: J. J. Baalbergen, J C Verstelle, A.J. Van Duyneveldt, T. S. Ong
Publikováno v: Le Journal de Physique Colloques. 49:C8-1065
Ac susceptibility measurements in spin glasses over an extended frequency range indicate a Cole-Cole behaviour at temperatures from well above to far below the freezing temperature. The consequences of this kind of relaxation are discussed.

On Spin‐Spin Relaxation Effects
Autor: J. C. Verstelle, C. J. Gorter
Publikováno v: Journal of Applied Physics. 39:834-836
Results of different series of observations recently carried out in Leiden on spin‐spin relaxation effects in paramagnetic salts of the iron group are reported and discussed. The character of the frequency‐zero band and the resonance bands in par
