Resistive switching behavior in Lu2O3 thin film for advanced flexible memory applications.

In this article, the resistive switching (RS) behaviors in Lu2O3 thin film for advanced flexible nonvolatile memory applications are investigated. Amorphous Lu2O3 thin films with a thickness of 20 nm were deposited at room temperature by radio-frequency magnetron sputtering on flexible polyethylene terephthalate substrate. The structural and morphological changes of the Lu2O3 thin film were characterized by x-ray diffraction, atomic force microscopy, and x-ray photoelectron spectroscopy analyses.

Development of an x-ray diffraction camera used in magnetic fields up to 10 T.

A high-field x-ray diffraction (HF-XRD) camera was developed to observe structural changes of magnetic materials in magnetic fields up to 10 T. The instrument mainly consists of a Debye-Scherrer-type camera with a diameter of 80.1 mm, a 10-T cryocooled superconducting magnet with a 100-mm room-temperature bore, an x-ray source, a power supply, and a chiller for the x-ray source.

Superconductivity of Ni-Nb-Zr-H glassy alloys with nanoclusters.

We investigated the hydrogen effect on superconductivity in the (Ni0.36Nb0.24Zr0.

X-ray diffraction measurements in high magnetic fields and at high temperatures.

A system was developed measuring x-ray powder diffraction in high magnetic fields up to 5 T and at temperatures from 283 to 473 K. The stability of the temperature is within 1 K over 6 h. In order to examine the ability of the system, the high-field x-ray diffraction measurements were carried out for Si and a Ni-based ferromagnetic shape-memory alloy.

Magnetic and structural phase transitions of MnBi under high magnetic fields.

High-field x-ray diffraction and magnetization measurements and differential thermal analysis (DTA) were carried out for polycrystalline MnBi with an NiAs-type hexagonal structure to investigate its magnetic and structural phase transitions. The lattice parameter rapidly decreases below the spin reorientation temperature (=90 K) in a zero magnetic field. The parameter decreases gradually with decreasing temperature and exhibits an anomaly in the vicinity of .
