ABSTRACTLa3+ doped yttrium iron garnet films have been grown on (111) oriented gadolinium gallium garnet substrates via Liquid phase epitaxy technique as a basic material for ISHE device fabrication. Pt as a material with a large spin hall angle was used as a spin detection layer. We investigated the dependence of the spin pumping effect on the power and frequency of the excitation microwaves in La:YIG/Pt bilayers by measuring the ISHE voltage. We demonstrated that the area under the ISHE curve(SISHE) across a wide power range had a nearly linear correlation with the input microwave power (Pin). The parameter SISHE can be used to describe the spin current energy in a Pt layer which can be a useful parameter for a microwave rectifier.

The room temperature magnetoelectric effect was observed in epitaxial iron garnet films that appeared as magnetic domain wall motion induced by electric field. The films grown on gadolinium-gallium garnet substrates with various crystallographic orientations were examined. The effect was observed in (210) and (110) films and was not observed in (111) films. Dynamic observation of the domain wall motion in 800 kV/cm electric field pulses gave the domain wall velocity in the range 30÷50 m/s. Similar velocity was achieved in magnetic field pulse about 50 Oe.

ABSTRACTThe growth technique, the micromorphological and microstructural characterization by means of atomic force microscopy (AFM) and secondary ions mass spectrometry (SIMS) as well as the magnetic properties of a novel class of magnetic multilayers, based on radio frequency (RF) sputtered thin amorphous garnet films, are presented. One, three and five thin film multilayers composed by amorphous pure yttrium iron garnet (a:YIG) and amorphous gadolinium gallium garnet (a:GGG) have been grown on GGG single crystal substrates. The multilayer interfaces have been found to be comparable in both, the three and five-layers structure. Low field susceptibility measurements, showed a paramagnetic behaviour for the single layer YIG film. For the three and five layers samples, irreversibility effects were observed, giving evidence of magnetic clusters at the interface YIG/GGG.

В данной работе с использованием комплекса экспериментальных методик и специализированного программного обеспечения исследуются магнитные висмутсодержащие феррит-гранатовые пленки, выращенные на подложках из гадолиний-галлиевого граната. Методом оптической магнитометрии получены предельные петли магнитного гистерезиса для дефектных и бездефектных участков висмутсодержащих феррит-гранатовых пленок. Установлено, что вдали от дефектов петля демонстрирует бескоэрцитивное поведение в пределах погрешности. Для случая перемагничивания вблизи дефекта появляется коэрцитивное состояние с H~1 Э. Для разных участков предельной петли магнитного гистерезиса определена фрактальная размерность. Полученные значения лежат в диапазоне D=1,35÷1,46 для произвольного участка пленки и D=1,37÷1,54 для участка с дефектами. Определены типичные морфологические характеристики поверхности висмутсодержащей ферритгранатовой пленки. Полученные результаты позволяют для эпитаксиальных висмутсодержащих магнитных пленок феррит-граната прогнозировать взаимосвязь между значением намагниченности и значением фрактальной размерности. In this work, using a set of experimental techniques and specialized software, magnetic bismuth-containing ferrite-garnet films grown on gadolinium-gallium garnet substrates are investigated. The limiting magnetic hysteresis loops are obtained by the method of optical magnetometry for defective and defect-free areas of bismuth-containing ferrite-garnet films. It was found that, far from defects, the loop exhibits a non-coercive behavior within the error limits. For the case of magnetization reversal, a coercive state with H ~1Oe appears near the defect. For different sections of the limiting magnetic hysteresis loop, the fractal dimension is determined. The obtained values are in the range of D=1,35÷1,46 for an arbitrary section of the film and D=1,37÷1,54 for a section with defects. Typical morphological characteristics of the surface of a bismuth-containing ferrite-garnet film have been determined. The results obtained make it possible to predict the relationship between the value of magnetization and the value of fractal dimension for epitaxial bismuth-containing magnetic films of iron garnet.
