Abstract

The effect of magnetic field on the structural phase transitions at low temperature in La2−x Sr x CuO4 has been investigated using the ultrasonic sound velocity experiment. An increase in the sound velocityV s is observed below ∼10K aroundx=0.12, which seems to be a precursor of the structural phase transition. This increase ofV s is drastically enhanced by applying a magnetic field. In case ofx=0.120, the temperature whereV s shows the upturn shifts from 5K(H=0T) to 12K(H=15T), whereas, inx=0.160,V s is not affected by magnetic fields up to 15T. These results suggest that the structure at low temperature (P 42 /ncm or Pccn) in La2−x Sr x CuO4 aroundx=0.12 is stabilized in magnetic fields.
