Individual‐Layer Thickness Effects on the Preferred c‐Axis‐Oriented BiFeO3 Films by Chemical Solution Deposition

“…Hence, the magnetization of thin BFO thin films is larger than the thicker one. For grain boundary increases and grain size decreases with increasing the thickness, the interaction of the uncompensated spins increase, which indicates that the magnetic ordering is further improved, 28 resulting in the further increase in T f . Similarly, the increase in grain boundary also results in the increase in the pinning of magnetization at the grain boundaries, 29 and further increases the magnetic coercivity.…”

Magnetic field annealing effects on self-oriented BiFeO3 thin films prepared by chemical solution deposition

“…Such rotation and alignment of the BFO crystallites result in enhancement of magnetization. Generally, decreasing uncompensated spins at BFO grain boundary and increasing alignment degree of the BFO crystallites with increasing annealing field lead to the magnetization and the magnetic interaction between different grains decreasing initially, and then increasing, which further results in the same variation of the spinglass transition temperature [23]. Additionally, the effect of texture difference resulting from magnetic annealing should be considered.…”

Surface-induced magnetism in C-doped SnO2

“…13 Recent theoretical calculations further showed that magnetism can be induced with NM impurities. 14,15 A good example of NM impurity is carbon, which has been recently predicted to induce magnetism in bulk materials. [16][17][18] All previous investigations focused mainly on bulk magnetism.…”
