Magnetic properties of nanosized mixed valent manganites CaMnO3 and Ca0.7La0.3Mn1−xCexO3 (x=0; 0.2)

Structural stability of calcium-manganate based CaO(CaMnO3)m (m = 1, 2, 3, ∞) compounds for thermoelectric applications

“…The CaMnO 3 phase exhibits an orthorhombic crystal structure with the Pnma space group symmetry [44,45]. In general, within a tolerance of 0.01 Å, the orthorhombic cell can be reduced to a cubic cell having the Pm3m symmetry with a unit cell parameter a =3.73 Å at room temperature [44][45][46].…”

“…In general, within a tolerance of 0.01 Å, the orthorhombic cell can be reduced to a cubic cell having the Pm3m symmetry with a unit cell parameter a =3.73 Å at room temperature [44][45][46]. We performed calculations for both PM forms of the crystal structures Pnma and Pm3m as well as for the G-AFM phase [44], which was found to be the ground-state phase at low temperatures (T N =120 K) [38,45]. To speed up calculations for the magnetically ordered phase, the cubic Fm3m crystal structure was used.…”

The effect of the annealing temperature on the structural and magnetic properties of the manganites compounds

“…In our previous articles we have studied the effect of the substitution of lanthanum by cerium on the physical properties of electron-doped manganites [9,10].…”

Magnetic properties of a non-equilibrium Al(Fe–Ni) alloy powder by rod-milling and chemical leaching

“…Also, a shift of the ZFC magnetization maximum to lower temperatures with an increase of the applied field as shown in Fig. 6 can be widely accepted to be valid in spin-glass systems [23]. Fig.…”
