Energy separation due to Jahn-Teller distortion (up) and depiction of trimeron concept in single Fe⁺²O₆ octahedra (down) (a) [8]. Changes in magnetic susceptibility, resistance, and specific heat at (b) [10, 17]. For clarity, the temperature scale for and was shifted concerning the true temperature scale. With an increasing number of vacancies or doped atoms, the VT shifts to low temperatures (c) [18].
