“…This mechanism has been verified by the epitaxial growths of a diverse set of materials, including Heusler alloys [169][170][171], FeGe [132], Co 25 Fe 75 [50], double perovskites [167,[171][172][173][174][175][176][177][178][179][180][181][182][183][184], and YIG [48,[113][114][115][116][117][118][119][120][121][122][123][124][125][126][127][128][129][130][131][133][134][135][136]. The deposition conditions for most materials are as follows: (1) sputtering gases: ultrahigh purity argon, plus 0% to 5% oxygen for oxides depending on the reduction-oxidation chemistry of the mat erials; (2) substrate location: off-axis angle 50° < β < 60°, substrate-to-target distance: 3.5″-4″; (3) substrate temper ature: 200°C-850°C depending on the materials; and (4) deposition rates: 5-120 nm h −1 depending on the materials and sputtering power, which is comparable to the deposition rates of...…”

“…To simultaneously address the problems of energetic bombardment and off-stoichiometry associated with conventional on-axis and high pressure off-axis sputtering, we developed a new off-axis sputtering technique in the past several years [168]. Using this new technique, we have successfully grown single-crystalline epitaxial films of a broad range of complex materials with a high degree of structural perfection and stoichiometric compositions, including Heusler compounds [169][170][171], B20-phase FeGe [132], Co 25 Fe 75 [50], double perovskites [167,[171][172][173][174][175][176][177][178][179][180][181][182][183][184], and YIG [48,[113][114][115][116][117][118][119][120][121][122][123][124][125][126][127][128][129][130][131][133][134][135][136].

Ferromagnetic resonance driven spin pumping, a topic of steadily increasing interest since its emergence over two decades ago, remains one of the most exciting research fields in condensed matter physics. Among the many materials that have been explored for spin pumping, yttrium iron garnet (YIG) is one of the most extensively studied because of its exceptionally low magnetic damping and insulating nature. There is a great amount of literature in the spin pumping and related research fields, too broad for this review to cover. In this Topical Review, we focus on the YIG-based spin pumping results carried out by our groups, including: the mechanism and technical details of our off-axis sputtering technique for the growth of single-crystalline YIG epitaxial films with a high degree ordering, experimental evidence for the high quality of the YIG films, spin pumping results from YIG into various transition metals and their heterostructures, dynamic spin transport in YIG/antiferromagnet hybrid structures, intralayer spin pumping by localized spin wave modes confined by a micromagnetic probe, dynamic spin coupling between YIG and nitrogen-vacancy centers in diamond, parametric spin pumping from high-wavevector spin waves in YIG, and localized spin wave mode behavior in broadly tunable spatially complex magnetic configurations. These results build on the power and versatility of YIG spin pumping to improve our understanding of spin dynamics, spin currents, spin Hall physics, spin-orbit coupling, dynamic magnetic coupling, and the relationship between these phenomena in a broad range of materials, geometries, and settings.

All-on-Chip Concurrent Measurements of the Static Magnetization and of the Electron Spin Resonance with Microcantilevers

A large variety of the samples of novel magnetic materials, which are of high interest due to their exotic properties, are only available in very small sizes. In some cases, it is not possible to synthesize large single crystals; in other cases, the small size itself is the key prerequisite to manifest a specifically interesting property of the material. The smallness of a sample rises a problem of the detection of the static magnetic response and of the electron spin resonance (ESR) signal. To overcome this problem, we propose to use a cantilever-based (torque-detected) setup with the capability of a simultaneous measurement of ESR and static magnetization. This setup offers a high sensitivity and the ability to acquire along with the ESR signal the components of the magnetization tensor in a single experimental run. Here, we present the working principle of this setup, as well as the estimate of its sensitivity from the measurements on the standard Co Tutton salt sample.
