Abstract

In this paper, we report on the magnetic and dielectric properties of HoMnO3nanoparticles with different size synthesized by a polymerized complex method have been investigated. The HoMnO3nanoparticles crystallized in hexagonal perovskite-type structure. The zero-field-cooled magnetic susceptibility curve of HoMnO3nanoparticles with averaged size of 30 nm shows that complicated magnetic transitions occurred in a temperature range from 2 to 100 K, which was confirmed by magnetic hysteresis loops. With increasing the particle size, the antiferromagnetic (AFM) transition temperature increases from 56 to 77 K, due to the reduced surface-to-volume ratio. Moreover, with a decrease in particle size, the Mn-spin reorientation temperature (TSR) is enhanced from 44 to 48 K.
