  •  
  • 日時:平成29年7月3日(月)16:00~17:00
    場所:工学部6号館1階103号室(大会議室)

    題目:新学術「複合アニオン」セミナー
    “Topochemical reduction and anion exchange as a route to novel electronic materials”
    概要:
    Transition-metal oxides are the subject of intensive study due to the wide variety of physical and chemical properties they can exhibit. However, the search for new transition-metal oxides is hampered by the refractory nature of metal oxides, which requires the majority of synthesis approaches to operate at high temperature under thermodynamic control, precluding the preparation of metastable phases and thus limiting the variety of compounds that can be prepared.
    The topochemical (structure conserving) manipulation of complex oxides offers access to metastable phases by exploiting the small differences in the low-temperature mobility of the different species in extended oxide lattices. For example, in many complex metal-oxide lattices the oxide anions are more mobile than the cations at low temperatures. Thus, if the correct reagents are used, oxide anions can be removed, inserted or exchanged, while the cation framework remains largely unchanged, allowing the preparation of phases which cannot be synthesised by conventional high-temperature routes.
    Binary metal hydrides can act as highly effective reducing agents for the extraction of oxide anions from complex transition metal oxides, allowing the preparation of novel phases containing transition metal centres in unusually low oxidations state and/or unusual coordination environments. Alternatively hydride-for-oxide anion exchange can occur to yield highly metastable oxide-hydride phases.
    By applying these reagents to complex oxides containing heavy transition metals, novel reduced oxide, or oxide-hydride, phases can be prepared which contain 4d or 5d transition metals (Ru, Rh, Ir) in extremely low oxidation states, and their electronic interactions studied.
    In this talk the synthesis and physical properties of a series of highly reduced 3d-4d and 3d-5d transition metal systems will be described and contrasted with the behaviour of ‘conventional’, oxygen stoichiometric phases.

    題目:Electrical control of magnetization via direct piezo-electro-magnetic coupling
    Abstract:
    The interplay between magnetic and electric properties of magnetic layers is of a considerable interest owing to the perspective of exploiting the underlying mechanisms for the next generation of devices for information storage and processing. Several different ways have been exploited for the control of the magnetization vector by an electric field – predominantly in metallic ferromagnets. Here we show a previously unforeseen phenomenon of piezo-electro-magnetic effect operating in one host: insulating dilute magnetic semiconductor (Ga,Mn)N. After a brief introduction to the magnetism in (Ga,Mn)N it be shown that the application of an electric field along a polar axis in this wurtzite magnetic compound leads to a sizable change of its crystalline magnetic anisotropy via the inverse piezoelectric effect. We investigate this phenomenon experimentally and describe theoretically in a paramagnetic Ga0.975Mn0.025N as a function of temperature, magnetic, and electric field.
