Magnetic and magnetocaloric properties of FeMnO3
Source abstract
Abstract
Abstract FeMnO 3 , prepared by mechano-synthesis method using high energy planetary ball mill, crystallizes in bixbyite type cubic structure in space group Ia 3. Magnetic measurements show that the compound is ferrimagnetic at room temperature and on cooling undergoes antiferromagnetic ordering around, T o ~ 36 K. Magnetization measurements exhibit strong magnetic anisotropy in this system. Change in the magnetic entropy, also known as the magnetocaloric effect, has been observed in FeMnO 3 on subjecting the sample to a changing magnetic field. We found maximum change of magnetic entropy ~1.5 J/kg K, for a field change of 90 kOe at T ~2 T o with relative cooling power of 50 J/kg.
