Non-uniform behavior of La0.7Sr0.3Co1−Mn O3 (y=0.3 and 0.5) compounds

Observation of mixed-phase behavior in the Mn-doped cobaltite La0.7Sr0.3Co1−xMnxO3 (x=0–0.5)

“…The quality of the samples was checked by powder X-ray diffraction. The results show that all the samples are single phase in structure, being assured for further research [6]. Magnetic measurements are carried out in a Quantum Design MPMS S5 and a MPMS XL (SQUID) at theÅngström Laboratory, Uppsala University, Sweden.…”

“…The variation of w with temperature can be used to reveal the magnetic character of the non-FM matrix. In the present work, initial magnetization M(H) curves in magnetic fields up to H=4T and at different temperatures are carried out for all the La 0.7 Sr 0.3 Co 1 À x Mn x O 3(x=0-0.5) samples[4,6]. The M S (T) and w(T) curves extracted from the M(H) measurements in the high-field regime are then discussed in terms of FM and non-FM mixed-phase behavior.…”

Mixed Phase Behavior in Hole-Doped Perovskite Materials

“…The case of mixing the two DE ions, Mn with Co, at B site seems to be very interesting and has, recently and currently, become the subject of various studies by our group [15,19]. It has been shown that the La 0.7 Sr 0.3 Co 0.9 Mn 0.1 O 3 compound exhibits clear evidences of SG behavior [15].…”

“…Based on electronic transport versus magnetic behavior our group have showed [8,[11][12][13][14][15][16][17]19,20], coexistence of FM/M and AFM/I states and glassy behavior in several manganites and cobaltites. The present paper reviews up-to-date results of our studies.…”
