“…In LPCMO-2 material, a small kink around 45 K is also observed which is due to spin freezing indicating re-entrant spin glass transition similar to reported in other manganites [33,34]. Fig.…”

“…Sankar et al [12] studied the magnetic properties of the self-doped lanthanum manganites, and deduced the anomalous low-temperature behavior mainly to some domain wall effects, which is associated with the degree of self-doping and Mn 4+ concentration. Sudyoadsuk et al [18] and Hasanain et al [19] believed that the anomalous decline is caused by re-entrant spin-glass transition and the spin freezing temperature is at T (~100 K). However, both of them have no direct evidence for their conclusions.…”

A systematic study on the structural, magnetic, and electrical transport properties was performed for the LaMn 1−x Cu x O 3 system. A single phase of orthorhombic perovskite structure was formed for x = 0.05-0.40. A striking paramagnetic-ferromagnetic transition and a considerable magnetoresistance effect were observed at the ferromagnetic ordering temperature T C , but no insulator-metal transition induced by Cu-doping was observed. Below T C , a visible unexpected drop was observed in the ac susceptibility and zero-field-cooled dc magnetization for the dilute doped samples with x ≤ 0.10, which was proven to be associated with domain wall pinning effects by milling the bulk material into single domain particles. It is validated that there is no exchange interaction between Cu and Mn, and double exchange interactions between Mn 3+ and Mn 4+ are induced by Cu-doping in the anti-ferromagnetic LaMnO 3 matrix, whereas the severe distortion and disorder caused by occupied-dopant prohibits charge carriers from hopping.

“…When such a system is cooled from high temperature, first there is a PM-FM transition at T c followed by a lower temperature transition to a state exhibiting spin freezing, such as a spin glass. Various CMR compounds have shown such a reentrant spin glass transition [13][14][15][16][17][18][19].…”
