Electroresistance Effect Due to Mo Substitution at Mn-Site in Monovalent Doped La0.85Ag0.15Mn1-xMoxO3 (x = 0.00 and 0.05) Manganites MUHAMMAD SYAZWAN Mohd Sabri1,a, NUR AIN ATHIRAH Che Apandi1,b and NORAZILA Ibrahim1,c* 1Faculty of Applied Sciences, Universiti Teknologi MARA, 40450, Shah Alam, Selangor, Malaysia asyazwanstar@gmail.com, baintrah@gmail.com, cnoraz954@salam.uitm.edu.my Keywords: electroresistance; mn-site substitution; monovalent doped manganites.
Introduction The electroresistance (ER) effect in divalent-doped manganites is due to the change in the spin alignments of Mn ions under increased electric field and makes the material attractive for further research related to the spintronic-based technology, such as nonvolatile memory elements [1-6].
