Different properties such as magnetization, coercivity, and remanence show evidence for changes in the magnetic properties associated with the phase transitions at low temperatures, reported from Raman studies. Detailed field-cooled and zero-field-cooled magnetization measurements show that the likely origin of the changes in the magnetic characteristics is from the changes in the domain structure.</p>10abismuth compounds10acoercive force10acrystallites10amagnetic domains10amagnetic transitions10aMultiferroics10aNanostructured materials10aRaman spectra10aremanence1 aVijayanand, S.1 aMahajan, Mangesh, B.1 aPotdar, H., S.1 aJoy, Pattayil, Alias  uhttps://library.ncl.res.in/content/magnetic-characteristics-nanocrystalline-multiferroic-bifeo3-low-temperatures-0
