The interaction of ferrite materials with radiation can be exploited to engineer substantially improved radiation detectors capable of revolutionizing medical imaging technology. It can also dramatically improve vital elements of telecommunication systems, functional microelectronics, and satellite technologies. In 2021, Dr. Albert's laboratory at Lakehead University reported the first-ever observation of a photoinduced nonlinear magnetoelectric effect (PNME). The PNME effect was observed to be approximately twice as strong as compared to the conventional magnetoelectric effect (ME). This invention demonstrated that further investigation of photosensitive magnetic materials and the changes to their radiation-induced magnetic properties is important to improve modern technology. Considering the high significance of this novel physical effect, Drs. Albert and Reznik's laboratories are conducting a research program dedicated to in-depth research on the PNME effect in different semiconductive ferrites to develop high-performance PNME-based microwave devices as well as the first hexaferrite-based radiation detector capable of rapid signal processing. The requested Rohde & Schwarz ZNB40 vector network analyzer provides the necessary wide frequency range and accurate measurement of the ferrite's intrinsic magnetic parameters for investigation of PNME. This novel research program will focus on the engineering and development of new ferrite materials with strong PNME effects, their further implementation in microwave devices such as filters and phase-shifters, and development of the first solid-state ferrite-based radiation detector. The outcomes of this research program will be highly beneficial for the Canadian economy and manufacturing sectors, will strengthen Canada's leading position in the international healthcare arena, and boost Canadian telecommunication and space technologies. The proposed research program will establish a novel cutting-edge research platform that will allow a completely new field of modern material science to be investigated at Lakehead University. This ground-breaking research will attract numerous international collaborations and will allow the training of highly qualified personnel in areas of magnetic materials, functional microelectronics, and medical imaging. The program is designed to encourage and increase the inclusion of under-represented groups in material science and technology, to enhance excellence in research and training with an open and diverse approach for trainees through best practices and continuous development. The successful completion of this program will constitute a fundamentally new material science research paradigm that will make Canada one of the leading countries in multiferroic material development. Establishing this advanced research platform and developing multitudes of national and international collaborations will be highly beneficial for the development of Northwestern Ontario.

铁氧体材料与辐射的相互作用可以用来设计能够彻底改变医学成像技术的实质性改进的辐射探测器。它还可以显著改善电信系统、功能微电子和卫星技术的关键要素。 2021年，湖首大学阿尔伯特博士的实验室报告了有史以来首次观测到的光致非线性磁电效应（PNME）。观察到的PNME效应是大约两倍强的相比，传统的磁电效应（ME）。本发明表明，进一步研究光敏磁性材料及其辐射感生磁性能的变化对于改进现代技术是重要的。考虑到这种新的物理效应的重要性，Albert和Reznik博士的实验室正在进行一项研究计划，致力于深入研究不同铁氧体中的PNME效应，以开发高性能的基于PNME的微波器件以及第一个基于六角铁氧体的辐射探测器，能够快速处理信号。所要求的罗德和施瓦茨ZNB 40矢量网络分析仪提供了必要的宽频率范围和精确测量的铁氧体的固有磁参数的研究PNME。这项新的研究计划将专注于具有强PNME效应的新型铁氧体材料的工程和开发，它们在滤波器和移相器等微波器件中的进一步实现，以及第一个基于固态铁氧体的辐射探测器的开发。这项研究计划的成果将对加拿大经济和制造业非常有益，将加强加拿大在国际医疗保健竞技场的领先地位，并促进加拿大的电信和空间技术。拟议的研究计划将建立一个新的前沿研究平台，将允许现代材料科学的一个全新的领域在湖首大学进行调查。这项突破性的研究将吸引众多国际合作，并将允许在磁性材料，功能微电子和医学成像领域培训高素质的人才。该计划旨在鼓励和增加材料科学和技术中代表性不足的群体的参与，通过最佳实践和持续发展，以开放和多样化的方式为学员提供卓越的研究和培训。该计划的成功完成将构成一个全新的材料科学研究范式，使加拿大成为多铁性材料开发的领先国家之一。建立这一先进的研究平台，发展众多的国家和国际合作将是非常有益的西北安大略的发展。
