Evolution of the magnetic and magnetotransport properties of the Ga-substituted manganite compounds La2-xSrxMnGaO6

Abstract:

We report a series of magnetic and magnetotransport studies performed on Ga-substituted manganite compounds La2-xSrxMnGaO6 (x≤0.7). We replace half of the Mn ions in LaMnO3 with diamagnetic ions Ga3+ and find that the system transforms into a ferromagnet as the result of local coherent and incoherent distortions. Following additional doping with Sr ions we find that the La2-xSrxMnGaO6 compounds remain ferromagnetic up to x∼0.3 but for higher concentrations the competition between the ferromag...
