“…It is possible to tune the electronic states of local sites on crystal surfaces by a high‐energy ion beam or laser irradiation . Laser irradiation has been utilized for inducing oxygen deficiency into TiO 2 , CaTiO 3 , and Sm 0.5 Ba 0.5 MnO 3 and for phase or structural transformation of α‐Al 2 O 3 to γ‐Al 2 O 3 , α‐Bi 2 O 3 to δ‐Bi 2 O 3 , tetragonal Cu 4 O 3 to monoclinic CuO, orthorhombic WO 3 ·H 2 O to monoclinic WO 3 , orthorhombic to monoclinic to cubic ZrO 2 , and tetragonal SrCuO 2 to orthorhombic SrCuO 2 …”

“…Laser irradiation of a wide variety of MO films and nanostructures has been conducted for their applications in dielectric, ferroelectric, piezoelectric, and multiferroic magnetoelectric devices, photocatalysis, gas sensors, transparent conductors, field‐effect transistors, solar cells, and thermistors ( Figure ). Besides the overarching goal of tailoring of the physical and chemical properties, several interesting phenomena induced by laser irradiation have been reported, e.g., structural distortion and transformation, diamagnetic to ferromagnetic switching, modification of exchange bias, wettability switching, p‐type to n‐type conductivity transformation, resistive switching, metal‐to‐insulator transition (MIT), and electrochromic switching …”

Recent technological advances in developing a diverse range of lasers have opened new avenues in material processing. Laser processing of materials involves their exposure to rapid and localized energy, which creates conditions of electronic and thermodynamic nonequilibrium. The laser-induced heat can be localized in space and time, enabling excellent control over the manipulation of materials. Metal oxides are of significant interest for applications ranging from microelectronics to medicine. Numerous studies have investigated the synthesis, manipulation, and patterning of metal oxide films and nanostructures. Besides providing a brief overview on the principles governing the laser-material interactions, here, the ongoing efforts in laser irradiation of metal oxide films and nanostructures for a variety of applications are reviewed. Latest advances in laser-assisted processing of metal oxides are summarized.

“…4 in Ref. 4, linearly increases with an increase in the incident laser power P (W) when the value is small, and subsequently seems saturated, which is due to heat dissipation by radiation to air. Here, temperature at the focal spot has been calculated from intensity ratios of the Stokes/anti-Stokes scattering, I Stokes /I ant-Stokes , at ½ µ 600 cm …”

We prepared SrCuO 2 thin film by radio-frequency magnetron sputtering on glass substrate and have investigated its postannealing effects on structure and thermal conductivity. The as-sputtered film belongs to two-dimensional spin system SrCuO 2 , namely, layer-type SrCuO 2 , which has a possibility of exhibiting high, anisotropic thermal conductivity by magnetic excitation of the spins. It was found that the as-sputtered film has (001)-orientation in which the spin layers are parallel to the surface of substrate and that post-annealing results in enhancement of crystallinity of the film such as disappearance of grain boundaries, which can cause an increase in thermal conductivity.©2017 The Ceramic Society of Japan.

The CuO 2 layer exhibits a two-dimensional arrangement of antiferromagnetically-coupled spins of S = 1/2 in Cu 2+ , referred to as spin layers. Moreover, the spin structure is expected to yield high thermal conductivity parallel to the layers by the magnetic excitation. However, researches on the crystal have been limited to those concerning high-pressure synthesis and epitaxial growth on single crystal substrate. This is because the crystal belongs to a high pressure phase and accordingly is instable in ambient air.
