Abstract / Description of output

Results of ultrasonic studies of the magnetoresistive compound Nd0.5Sr0.5MnO3 in a broad temperature range (1.5-180K) are reported. With decreasing temperature the pronounced acousticniode hardening was observed at about T-CO = 145 K. The change of sound velocity around T-CO was explained by a strong coupling between the acoustic phonons and the charge-ordered states. (C) 2001 Elsevier Science B.V. All rights reserved.
