Abstract

Thin films with properties comparable to bulk single crystals were grown by pulsed laser deposition using a substrate temperature of only 500 °C. This was achieved by a careful choice of both the oxygen pressure in the deposition chamber and the temperature of the air anneal. The best films were grown on gadolinium gallium garnet substrates but we also report data for films grown on the diamagnetic substrate yttrium aluminium garnet. The films were analysed using X-ray diffraction, near edge X-ray absorption and magnetometry. Our best films had a magnetisation of 143 emu/cm³ and a coercive field of ∼1 Oe.

A review of common materials for hybrid quantum magnonics
2023, Materials Today Electronics
Hybrid magnonics is an emerging research area focusing on various types of interactions between magnons (quantized collective spin excitations) and other information carriers, which has found broad practical applications ranging from high-precision magnetometry and thermometry to quantum transduction and neuromorphic computing. In this paper we review different types of hybrid magnonic devices, and the materials that are commonly used in each device type. We also discuss recent trends in the exploration of new materials and interaction mechanisms, and future research challenges and opportunities.
Strain-induced magnetic anisotropy of REIG thin films grown on YAG(111) substrates by pulsed laser deposition
2022, Journal of Alloys and Compounds
Citation Excerpt :
In the following, room temperature investigations on magnetic anisotropy of REIG are briefly summarized. According to previous reports [15,18–19,24–25,27, 34–38], YIG thin films grown on GGG or YAG substrates have the magnetic easy axis parallel to the film surface due to significant shape anisotropy and negligible magnetocrystalline anisotropy. As a result, Rosenberg et al. [20] proposed that the magnetic easy axis switches to the out of the film plane by substituting yttrium with rare-earth (RE) elements.
Several studies have revealed using rare earth (RE) elements instead of yttrium to regulate the strain-induced magnetic anisotropy of garnet films in recent years. In this study, we used pulsed laser deposition to fabricate RE iron garnet (REIG) thin films on (111)-oriented yttrium aluminum garnet (YAG) substrates. The REIG films are 100 nm in thickness and crystalline with (111)-orientation. The out-of-plane (444)-plane spacing decreases as the ionic radius of RE metal ions decreases, while the crystallite size increases. Samarium, holmium, and yttrium iron garnet (SmIG, HoIG, and YIG) have out-of-plane compressive strain, while erbium and thulium iron garnet (ErIG and TmIG) have weak out-of-plane tensile strain. The strain of the REIG films is resulted from lattice mismatch, off-stoichiometry, and the recrystallization process by thermal annealing. SmIG has a rather rough surface because of the crystalline distortion due to the largest ionic radius of Sm and the lattice mismatch between SmIG and YAG substrates. Due to negative magnetostriction constant and out-of-plane compressive strain, SmIG and HoIG films show strong perpendicular magnetic anisotropy (PMA) in vibrating sample magnetometry and magneto-optical Faraday effect (MOFE). MOFE also revealed that the REIG films have different sensitivities at different wavelengths of light. With further tuning PMA on SmIG and HoIG by decreasing the thickness and lateral size, our findings could pave the way for high-density nano-scale magnetic information storage based on REIG thin films.
Magnetoimpedance effect in ferrimagnetic insulator yttrium iron garnet films capped by copper
2019, Journal of Magnetism and Magnetic Materials
Citation Excerpt :
Yttrium iron garnet (Y3Fe5O12; YIG) has received renewed interest lately as a key material for spintronics due to its unique magnetic properties — YIG is a ferrimagnetic insulator with low magnetization damping [1–6] and long spin-wave propagation lifetime [7,8]. Traditionally, single crystal YIG films have been grown onto lattice-matched substrates, as gadolinium gallium garnet (Gd3Ga5O12; GGG) [4–6], employing techniques as, for instance, pulsed laser deposition [4–6,9–12], liquid phase epitaxy [13,14], and magnetron sputtering [2,3,15–18]. Since YIG is an insulator, it is free from parasitic heating effects due to charge currents [19], which is particularly attractive from the technological perspective [17] for energy-efficient devices.
We investigate the magnetization dynamics through magnetoimpedance effect in films of ferrimagnetic insulator yttrium iron garnet capped by copper. Thereby, we explore the magnetoimpedance in systems with magnetic insulators by varying the thickness of the magnetic material, and probe current frequency. We observe that the difference of electrical nature of the layers composing the films gives rise to the magnetoinductive effect in the whole frequency range, as well as favors the appearance of the ferromagnetic resonance effect even at low frequencies. We discuss the experimental results in terms of the structural features of the magnetic material, its magnetic properties, and the different mechanisms governing the magnetization dynamics. The results place the films of ferrimagnetic insulator yttrium iron garnet capped by copper exhibiting magnetoimpedance effect as very attractive candidates for application as probe element in magnetic sensors operating at low frequencies and with energy-efficient technologies. Further, we disclose an auspicious technique to look at the magnetization dynamics in magnetic materials and we provide a new perspective to solve questions related to the integration of insulator ferrimagnetic materials with the coplanar waveguide in broadband frequency applications.
