58. The minor peaks observed in Fig. 6 may be explained by the minor magnetic ordered components indicating Hint =10-20 tesla. Total fraction of the magnetic components is less than 12 vol%.

61. The increase in the recoil-free fraction, which corresponds to the increase in effective thickness with decreasing temperature, induces acceleration of the time decay of the excited state (Ref.). This effect is called the speed-up effect. Therefore, if we do not measure the time spectrum from the time prompt synchrotron-radiation pulse that excited the nucleus, an increase in the effective thickness (recoil-free fraction) sometimes causes a decrease in the "delayed intensity." To avoid the effects of a strong prompt synchrotron-radiation pulse, delayed components were measured from 3 ns after the pulse in our measurement. As shown in Fig. 8, the delayed intensity decreases as the temperature is lowered to TN although this is contrary to what is expected from the increase in the recoil-free fraction. However, the appearance of the hyperfine splitting decreases the effective thickness for the degenerated state, explaining the observed increase in the delayed intensity as the hyperfine splitting increases below TN.

63. Provided that the magnetic moment of an ion is proportional to the internal magnetic field (Hint), the conversion factor (CF) is defined by the relation between the ion's magnetic moment (μ) and internal magnetic field (Hint) using the Lande g factor (gLande) and the total angular-momentum quantum number (J): μ/ μB = gLande J | Hint /CF |. On the other hand, Hint of a rare-earth ion is obtained from the relationship using the magnetic hyperfine splitting constant (JA) and nuclear g factor (gn)

65. as follows: - Hint = (JA) (106 Hz) 762.28 gn (106 G). The equation transforms into J= 762.28 gn A Hint. JA of S 149 m is calculated as -495, which is converted from the JA of S 147 m (=- 600 (S1)) using a ratio of dipole interaction constants A147 / A149 (=1.21302)

67. Then, A is calculated as -197.86 using J=5/2 for Sm3+ (4 f5 5 s2 p6). gn is calculated as -0.191 using a nuclear magnetic moment of S 149 m (-0.6677 μn) and a nuclear-spin quantum number of S 149 m (7/2). (S3) http://ie.lbl.gov/ensdf/

69. μn denotes nuclear magneton. Therefore, 476 tesla/ μB is adapted for the CF of S 149 m3+ using the following equation: CF Hint gLande J = A 762.28 gLande gn ≅4.76 (106 G/ μB) =476 (tesla/ μB). This value is the same as that obtained by Barla
