Abstract
A systematic study on the effect of strontium (Sr) doping in YMnO3 has been undertaken. Polycrystalline samples with composition Y1-xSrxMnO3 (x=0, 0.01) were synthesized by using high temperature solid state reaction method. The structural and thermal properties of the prepared samples have been carried out in the wide range of temperature. Our XRD reveals the single phase formation of the reported compounds in hexagonal structure with space group P63cm (JCPDS: 25-1079). The observed pointed kinks in the specific heat study are symptomatic of the probable coupling in between the electric and magnetic orders. Our specific heat curves show that the AFM transition temperature (TN) shifts to higher value with minute Sr doping to Y-site. Further, low temperature study shows independence of specific heat on magnetic field at 8T and 12T.
