Effects of copper doping on the structure, electrical and low-field magnetoresistance properties of (1–x)La0.67Sr0.33MnO3/xCu (x=0–0.15) composite coatings

Role of Fe (x = 0–0.15) Substitution on Structural, Magnetic, and Transport Properties of the La0.7Sr0.3FexMn1−xO3 System

“…The substitution of the transition metal at Mn sites disrupts the Mn 3+ -O 2--Mn 4+ chain leading to the alternation of the Mn 3+ /Mn 4+ ratio. Previous research has investigated doping with other transition metals including Cu, Fe, Ni, Co, and Ru at the Mn site in the LSMO system 11,[18][19][20][21][22][23][24] . Substitution at the Mn-site with transition metals has been reported to have a significant effect on the magnetic and transport behavior of LSMO 18 .…”
