摘要: Both magnetization and magnetic anisotropy of CoMn x Fe2- O4 particles composed the Jahn–Teller (JT) Mn3+ Co2+ions with an expected large magnetoelastic effect were investigated. prepared by using a molten salt method KBr as fluxing agent. A tetragonally distorted spinel structure was confirmed for ${x} =1.3$ or higher. This suggests that increase in Mn3+ions causes JT distortion c/a >1 . However, Mn3+doping spin canting decreased magnetization. saturation $M_{s} =44$ emu/g high coercivity $H_{c} =4300$ Oe observed sample =1.4$ at 10 K. In addition, field, $H_{A}$ , $H_{c}$ increased increasing ${x}$ from where first observed.
