A new publication has just appeared in the November 2016 issue of  Physical Review B. A study of the nature of phase transitions in high sensitivity piezoelectric KNN ceramics is reported. This results from our collaboration with Michel Venet’s group at the Federal University of São Carlos (Brazil).
