Jh. Zhao et al., Indirect evidence for spin-diffusion modes in La0.67Ca0.33MnO3 from field-dependent ac susceptibility measurements, PHYS REV B, 59(13), 1999, pp. 8391-8394
Field- and temperature-dependent measurements of the ac susceptibility in p
olycrystalline samples of La0.67Ca0.33MnO3 in the vicinity of the paramagne
tic to ferromagnetic transition temperature, T-c, reveal the presence of fe
atures qualitatively consistent with the presence of spin-diffusion modes.
