  Quantum phenomena, including entanglement, superposition, tunneling, and spin–orbit interactions, among others, are foundational to the development of recent innovations in quantum computing, teleportation, encryption, sensing, and new modalities of electronics, such as spintronics, spin-orbitronics, caloritronics, magnonics, twistronics, and valleytronics. These emerging technologies provide disruptive influences to global commercial markets. These remarkable advances in quantum technologies are nearly always enabled by the discovery of materials and their quantum behaviors. Such advances are governed by quantum principles that are strongly influenced by environmental, physical, topological, and morphological conditions such as very small length scales, short time durations, ultrahigh pressures, ultralow temperatures, etc., which lead to quantum behaviors that manifest as quantum tunneling, entanglement, superpositioning, superfluidity, low-dimensional, high-temperature and high-pressure superconductivity, quantum fluctuations, Bose–Einstein condensates, topological effects, and other phenomena that are not yet fully understood nor adequately explored. Here, we provide a review of quantum materials developed up to 2023. Remarkable advances in quantum materials occur daily, and therefore, by the time of publication, new and exciting breakthroughs will have occurred that are regrettably not covered herein.

  Transition from fourth to fifth generation wireless technologies requires a shift from 2.3 GHz to Ka-band with the promise of revolutionary increases in data handling capacity and transfer rates at greatly reduced latency among other benefits. A key enabling technology is the integration of Ka-band massive multiple input–multiple output (m-MIMO) antenna arrays. m-MIMO array elements simultaneously transmit and receive (STAR) data providing true full duplexing in time and frequency domains. A necessary innovation calls for the integration of device quality Ka-ferrites with wide-bandgap (WBG) semiconductor heterostructures allowing for system on-wafer solutions. Here, we report results of systematic studies of pulsed laser deposited (PLD) barium hexaferrite (BaM) films on industrial compatible WBG semiconductor heterostructures suitable for operation in Ka-band circulators.

• Crystallographically Textured and Magnetic LaCu-Substituted Ba-Hexaferrite with Excellent Gyromagnetic Properties

  Materials · 2022-12-09 · 4 citations

  articleOpen accessSenior author

  Excellent gyromagnetic properties of textured, bulk Ba-hexaferrite samples are required for low-loss, self-biased applications for microwave and millimeter-wave (MMW) devices. However, conventionally processed bulk Ba-hexaferrite ceramics typically demonstrate low remanent magnetization values, 4πMr, of 2.0~3.0 kG, and relatively large ferromagnetic resonance (FMR) linewidths, ΔHFMR, of 0.8~2 kOe. These properties lead to the development of high-performance, practical devices. Herein, crystallographically textured Ba-hexaferrite samples, of the composition Ba0.8La0.2Fe11.8Cu0.2O19, having excellent functional properties, are proposed. These materials exhibit strong anisotropy fields, Ha, of ~14.6 kOe, high remanent magnetization, 4πMr, of 3.96 kGs, and a low ΔHFMR of 401 Oe at zero-bias field at the Q-band. Concomitantly, the broadband millimeter-wave transmittance was utilized to determine the complex permeability, μ*, and permittivity, ε*, of textured hexaferrites. Based on Schlöemann’s theory of complex permeability, μ*, the remanent magnetization, 4πMr, anisotropy field, Ha, and effective linewidth, ΔHeff, were estimated; these values agree well with measured values.

  2022-11-04 · 2 citations

  otherSenior author

  Tackling thermal management and power consumption challenges, one aims to suppress inductor core power loss (CPL), as one of the major sources of inefficiency in these systems and is the main focus of this chapter. Novel designs and synthesis strategies are proposed for addressing dissipation mechanisms responsible for efficiency of inductor cores at high operating frequencies. Findings presented show remarkable suppression of the CPL by means of significantly reducing eddy currents and residual losses in MnZn-ferrite-based nanocomposites. The chapter presents a review of spinel ferrite compositions and structures with special attention paid to grain boundary chemistry and structure and its role in determining inductor performance in power generation, conversion, and conditioning applications. Ferrite compositions and ceramic processing protocols, including complex sintering practices, are reported and discussed at length as to their impact upon frequency-dependent performance.
