We observe the negative shift of the magnetic hysteresis loop at 5 K, while the sample is cooled in external magnetic field in case of 30% of Fe substitution in LaMnO<Subscript>3</Subscript>. The negative shift and training effect of the hysteresis loops indicate the phenomenon of exchange bias. The cooling field...</subscript>
