概要
- 論文の詳細を見る
The effect of B-site substitution on the critical behavior has been investigated in Cr-doped manganites La_<0.7>Ca_<0.3>Mn_<1-χ>Cr_χO_3 (χ = 0.00, 0.03 and 0.06) by means of the pump-probe method. We have observed that the Cr-doping suppresses the critical behavior of the relaxation time τ. This suppression has been interpreted in terms of a reduced correlation length of the photoinduced charge-ordering fluctuations due to the B-site impurities.
