The polycrystalline NdMn₂O₅ multiferroic was synthesized by wet chemistry method followed by heat treatment at 1000 °C. The structure was confirmed by X-ray diffraction (XRD) as orthorhombic with space group Pbam. The particle size and strain were calculated by Williamson-Hall method. Both infrared (IR) active and Raman active phonons have been observed using IR reflectivity and Raman spectroscopies. UV–visible absorption spectrum suggests that a possible optical band E_g ∼ 1.27 eV has been determined using Kubelka–Munk function. Magnetic field (2 T) dependent magnetization at room temperature suggests the paramagnetic nature of present compound. In addition, frequency-dependent dielectric properties (20Hz–30 GHz) indicate variation in dielectric constant, dielectric loss, tangent loss, as well as AC conductivity, in two distinct dielectric responses which are in accord with Debye relaxation model.
