초록

We have fabricated (0001) oriented hexagonal $HoMnO_3$ thin films with thickness of 300 nm using Pulsed Laser Deposition (PLD) technique on $Pt(111)/Ti/SiO_2/Si$ substrates. The XRD $\theta-2\theta$ pattern shows only (0002), (0004), and (0008) reflection of a hexagonal phase, and the full width at half maximum (FWHM) of (0004) peak is under $1.6^{\circ}$. The chemical state of Mn from XPS spectra of the films reveals the presence of $Mn^{3+}$ only. The temperature dependence of dielectric constant shows a weak anomaly at magnetic $N\acute{e}el$ temperature $(T_N)$, which is about 70 K.
