Abstract :
Doped perovskite manganites La1-xAxMnO3 with alkaline (or alkaline-earth) ions A have received considerable attention due to their interesting magnetic, magnetoresistive, and microwave properties [1-3]. Such compounds are examples of materials with complex magnetic orderings which exist over wide temperature and concentration ranges [4-7]. However, to date, the properties of these materials in the vicinity of magnetic ordering temperatures have been poorly studied. In this work, we investigate peculiarities of magnetic phase transition near magnetic ordering temperature of La1-xBixMnO3+δ with the use of electron spin resonance (ESR) technique.
