(a) The temperature dependence of specific heat \(C_{p}(T)\) of polycrystalline samples of BMTO in the temperature range 2 K \(\le\) T \(\le\) 250 K at zero applied field. The solid line is the fit of \(C_{p}(T)\) data to Debye \(+\) Einstein model accounting for the lattice contribution to specific heat. (b) The temperature dependence of magnetic specific heat (\(C_{mag}(T)/T)\) of BMTO in the temperature range 2 K \(\le\) T \(\le\) 50 K (left y-axis) and the calculated entropy change with temperature (right y-axis).
