摘要: Magnetic neutron spectroscopy of ${\mathrm{SMFe}}_{11}$Ti reveals a dispersionless electronic excitation corresponding to transitions between levels the exchange-split ground- and first-excited-state multiplets ${\mathrm{Sm}}^{3+}$ ion. The observed energy 175.5 meV at T=20 K may be accounted for in framework an exchange crystal-field model by assuming bare spin-orbit splitting 129 J=5/2 7/2 multiplets. data are explained with same parameters used fit experimental magnetization curves single-crystal ${\mathrm{SmFe}}_{11}$Ti.
