The Effect of Spin-Peierls Instability Suppression in Nanometer-Scale-Sized CuGeO3 Crystals
In this work, we study the influence of size effects on magnetic properties of quasi-one-dimensional spin-Peierls magnet CuGeO 3 . It was found that the reduction of the crystallite’s size to nanometer scale (~300 × 30 nm) leads to full suppression of spin-Peierls transition, which takes place in th...
