Critical Exponent in Normal to Incommensurate Phase Transition in KSc(MoO4) by EPR
The behaviour of KSc(Mo04) below the second order transition between the paraelastic and the incommensurate phase has been studied by means of EPR. It has been shown that a value of the critical exponent β describing the temperature dependence of the separation between edge singularities changes from 1.0 just below TI to 0.4 far below TI.
