Crossover of critical behavior in La0.7Ca0.3Mn1−xTixO3

Monte Carlo study of the critical behavior and magnetic properties of La2/3Ca1/3MnO3 thin films

“…In the last decades, intensive research has been focused on perovskite colossal magnetoresistance (CMR) manganites due to their interesting phenomena [1,2]. It has been recognized that the interesting properties are fundamentally originated from the double exchange (DE) mechanism between Mn 3 + -O-Mn 4 + [3] although some debate continues.…”

Critical behavior studies in Ti-substituted lanthanum bismuth perovskite manganites

“…Similar kind of critical analysis for Ti substitution has been studied in LaMn 0.9 Ti 0.1 O 3 [12,13], La 0.7 Ca 0.3 Mn 0.9 Ti 0.1 O 3 [14] and La 0.57 Nd 0.1 Pb 0.33 Mn 1−x Ti x O 3 [15]. The substitution of Ti at Mn site gives rise to inhomogeneous short range interactions in the magnetic ordering M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 3 around T C .…”

“…The substitution of Ti at Mn site gives rise to inhomogeneous short range interactions in the magnetic ordering M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 3 around T C . And the Ti substituted samples mentioned above studied by other researchers explicitly confirm this short range ordering which falls under 3D Heisenberg (HM) universality class [12][13][14][15]. Further Xuebin Zhu et al [14] clearly observed that the low Ti substituted sample La 0.7 Ca 0.3 Mn 0.95 Ti 0.05 O 3 show the characteristics of long-range interactions and for the higher Ti substituted sample, La 0.7 Ca 0.3 Mn 0.9 Ti 0.1 O 3 gives the evidence of spinglass like characteristics with short-range magnetic interactions [14].…”

La1-xCexMn2Si2 (x=0.35 ve 0.45) kritik davranışının manyetik entropi değişim bağlılığına göre araştırılması

“…The obtained critical exponents (β, γ, δ, and TC) can be also verified by the prediction of the scaling theory in the critical region. According to the scaling theory, the magnetic equation of state can be written as [31,32]:…”
