Magnetostructural stabilities. mechanical behaviors and electronic structures of various phases of manganese tetraboride (MnB4) have been investigated systematically by density functional theory (DFT) based first-principles methods. It is found that MnB4 undergoes temperature-induced phase transitions from the nonmagnetic (NM) monoclinic mP20 structure to the ferromagnetic (FM) orthor... https://www.maximilianopellegrini.com/product-category/c-vitamin-serum-2/
