Study of the Ultraslow Critical Dynamics of the Order Parameter of the Ferroelectric AgNa(NO2)2 by the Spin Relaxation Times T1, T1ϱ, T2 of the 23Na Nucleus
Abstract:Measurements are made of the temperature dependences of the spin relaxation times T,, TI,, and Tz of the "Na nucleus in the uniaxial ferroelectric AgNa(NO,),. Although none of these quantities shows an anomalous behaviour near T, their temperature dependences can be ascribed t o the dynamics of the electric dipoles which cause the ferroelectricity.Es wird iiber Messungen der Temperaturabhiingigkeiten der Spin-Relaxationszeiten T,, TI, und T2 des 2SNa-Kernes in dem uniaxialen Ferroelektrikum AgNa(NO,), berichte… Show more
