Transport properties of Cs doped Pr2/3(Ba1−xCsx)1/3MnO3 manganites

Double metal–insulator peaks and effect of Sm3+ substitution on magnetic and transport properties of hole-doped La0.85Ag0.15MnO3

“…2). Similar behaviors were also reported for La 1 À x Ag x MnO 3 [8], La 0.67 Ca 0.33 Mn 0.93 Fe 0.07 O 3 [15], Pr 2/3 (Ba 1 À x Cs x ) 1/3 MnO 3 [18], [24,[26][27][28] and Pr 0.67 A 0.33 MnO 3 [36]. The observed decrease in T c values with increasing Sm 3 þ shows that the ferromagnetic transition was weakened by the Sm 3 þ substitution for La.…”

“…The T c values were determined based on the minimum point of differentiation, dw 0 /dT versus temperature curves ( Fig. 3) [18,34,35]. In addition, for all samples, a decreasing trend was observed for w 0 below T c ( Fig.…”
