Description
Oxygen isotope effect on the charge-ordering transition was studied in La0.5Ca0.5MnO3. Upon replacing 16O with 18O, the charge-ordering temperature increases by 9 K under zero magnetic field. With an increase of the magnetic field, the oxygen isotope shift increases rapidly and reaches a magnitude of about 40 K under a magnetic field of 5.4 T. The present results cannot be explained by the existing theories of the charge-ordering transition in manganites. copyright 1999 The American Physical Society
