Quantum phase transitions play a key role in the understanding the phenomena of many-body systems, especially in anti-ferromagnetic magnetic plateaus. By means of variation mean-field-like treatment based on the Gibbs–Bogoliubov inequality, it is presented the frustrated magnetization plateau and thermal concurrence properties in spin-1/2 Ising–Heisenberg models on a triangulated Kagom´e lattice and a diamond chain. …
