Interplay between static cooperative Jahn–Teller distortion and magnetic properties ofoptimally doped manganites

Abstract

An effect of the static long range cooperative Jahn–Teller (JT) distortion on themagnetic properties of (A = La, Pr, Nd; , Sr) manganites with the orthorhombic structure ofPnma symmetry is studied on the basis of structural, magnetic and transport properties data. Adirect relationship between the static JT distortion parameter and the Curie temperaturewas found. The relationship between the static long range cooperative JT distortion,strength of electron–phonon coupling effects and magnetic properties of manganites is discussed.
