“…The M -H curve of the YIG film in Fig. 2(d) shows that the coercive force of the YIG film is very small (smaller than 5 Oe) and the saturation magnetization is 4πM s =1710 G (close to the bulk value [39]). These sample characterizations clearly confirm that our YIG films are of very high quality.…”

The longitudinal spin-Seebeck effect (LSSE) has been investigated for Pt/yttrium iron garnet (YIG) bilayer systems. The magnitude of the voltage induced by the LSSE is found to be sensitive to the Pt/YIG interface condition. We observed large LSSE voltage in a Pt/YIG system with a better crystalline interface, while the voltage decays steeply when an amorphous layer is introduced at the interface artificially.

“…These experimental results led to the conclusion that strain and oxygen stoichiometry were key factors in determining the magnetic properties of the STF and STCo films (factors that are also important in many other oxide systems [29,32]), but there are few reports on the effect of oxygen pressure during growth [33,34], and polycrystalline films have not been investigated. We report on the correlations among the microstructure, valence, and distribution of the Fe ions as well as the room-temperature magnetic properties of STF films as a function of base pressure P, characterized by high-resolution x-ray diffraction (XRD), transmission electron microscopy (TEM), Faraday rotation (FR), magnetometry, and Mössbauer spectroscopy.…”

Magnetism and Faraday Rotation in Oxygen-Deficient Polycrystalline and Single-Crystal Iron-Substituted Strontium Titanate

et al. 2017

Both polycrystalline and single-crystal films of iron-substituted strontium titanate, SrðTi 0.65 Fe 0.35 ÞO 3−δ , prepared by pulsed laser deposition, show room-temperature magnetism and Faraday rotation, with the polycrystalline films exhibiting higher saturation magnetization and Faraday rotation. The magnetic properties vary with the oxygen pressure at which the films are grown, showing a maximum at pressures of approximately 4 μ Torr at which the unit-cell volume is largest. The results are discussed in terms of the oxygen stoichiometry and corresponding Fe valence states, the structure and strain state, and the presence of small-volume fractions of metallic Fe in single-crystal films grown at the optimum deposition pressure. Integration of magneto-optical polycrystalline films on an optical-waveguide device demonstrates a nonreciprocal phase shift.

“…Существование переходного слоя в пленке ЖИГ было обусловлено диффузией немагнитных ионов Gd 3+ , Ga 3+ методом жидкофазной эпитаксии [22,23] и методом ионно-лучевого распыления [24]. Было установлено, что в пленках ЖИГ, выращенных методом жидкофазной эпитаксии, толщина переходного слоя может составлять 0.2−0.5 µm [23].…”

Показано, что в переходном слое эпитаксиальной пленки ЖИГ возникают эффекты коллинеарного магнитоупругого взаимодействия обменных спиновых (ОСВ) и акустических волн (АВ). Наиболее интенсивное взаимодействие происходит на частотах фазового синхронизма ОСВ и АВ. При этом появляются эффекты гибридизации и преобразования энергии ОСВ -> АВ. Выполнение условия синхронизма обеспечивается трансформацией длин ОСВ в пределах толщины переходного слоя. Вдали от точек синхронизма связь ослабляется, волны распространяются независимо друг от друга. При этом акустическая волна может беспрепятственно излучаться вглубь немагнитной подложки пленки железоиттриевого граната. В перспективе это может быть полезным для обеспечения фононной связи спин-волновых возбуждений в пленках, расположенных на противоположных сторонах немагнитной подложки. Ключевые слова: спиновые волны, магноника, фотоника, эпитаксиальные пленки.
