Optical And Magnetic Properties

Abstract Yttrium orthoferrite (YFeO3) is of considerable interest for its potential application in magnetic field sensors and magneto optical data storage devices. Doping is one of the effective approaches to tune the compound properties. And it is important to determine the doping sites of the dopants to better understanding the related mechanism. In this work, Manganese (Mn) doped YFeO3, i.e., YFMxO powders with 0 ≤ x ≤ 0.1 were synthesized by hydrothermal method to study the influences of doping on their structural, morphological, local electrical, optical and magnetic properties. The experimental results show that Mn dopants occupy Iron (Fe) sites and that all these samples exhibit an orthorhombic structure with space group Pnma. Refined structure parameters are presented. Morphology images show the shape evolution from layered to multilayered with increasing Mn content. The Fe and Y K-edge local structure studies indicate that the valency of Fe and Y is mainly found in trivalent state, which also indicate that substitution of Mn ions not only affects the nearest neighbor atomic shell of Fe but also affects the nearest neighbor’s local structure of Y atoms. IR spectra reveal the characteristic vibrations of the obtained YFMxO samples. From the magnetic study, it is observed that the substitution of Y ions by Mn ions changes the magnetic property of YFeO3 from ferromagnetic to paramagnetic. Our results show that the addition of Mn exhibits an evident influent on the local structural and magnetic properties.

Demands for the high storage capacities and rates of data transfer have been overwhelming in the recent years. With the increasing use of multimedia, the rewritable optical phase-change disks, e.g. CD and DVD, have become more popular. The optical PC data storage devices provide relatively short data access rates (∼ 10 MHz) and moderate areal densities. As in other areas of data storage, there has been tremendous demand and pressure, driven by consumer application, for inexpensive high-density PC systems. So far, the optical data storage industry has managed to meet the demands by using lasers with shorter wavelengths and objective lenses with higher numerical aperture (NA). Several strategies such as “multilevel storage layers” [1] and “mark radial width modulation” [2] have been proposed for the next generation of the high-density PC data storage devices. There have been advances in near field optical techniques to increase density (40 Gb/in) using solid immersion lens [3]. Hosaka et al. [4] demonstrated 60 nm domains in phase change media that translates to 170 Gb/in2 using a scanning near-filed optical microscope. Kado and Tohda [5] used an atomic force microscope (AFM) to locally modify the electrical property (×100) of a PC material by applying an electrical pulse between the probe and media. They achieved an areal density near 1 Tbits/cm2.

Oxide Melts

Several copper vanadium oxide melts were tested for possible application as the active medium in phase-change optical data storage devices. These materials were melted in the bulk and then quenched. Their phase development was characterized to help determine their applicability to optical data storage. It was found that they satisfy many of the criteria necessary for successful phase-change data storage; further studies of their behavior in thin film geometry would be warranted.
