Call for tender – MAGISTRAL Project
项目背景与目标
法国SPINTEC实验室的自旋绝缘电子学团队于2025年获得PEPR SPIN计划的探索性资助，启动为期四年的"MAGISTRAL"项目（全称：磁性圆盘作为角动量转换器）。该项目旨在开发新型超高保真光机械调制器，工作频率达GHz范围，并将亚铁磁材料集成至光学元件中。项目已于2025年3月1日启动。
关键技术需求
为实现目标，项目需获取具有极低磁损耗与声学损耗的磁性薄膜。当前最优材料体系为钇铁石榴石（YIG）单晶薄膜，需通过液相外延（LPE）技术生长在钆镓石榴石（GGG）衬底上。该材料已知损耗最低，是项目成功的关键。
招标内容
现需招募液相外延（LPE）技术专家，特别是针对石榴石材料生长经验者，以协助格勒诺布尔团队掌握该生长工艺。合作形式为分包任务，具体条款详见招标文件。
申请方式与截止时间
申请人需通过电子邮件向SPINTEC的Olivier KLEIN提交申请材料，截止日期为2026年4月30日（含当日）。详细申请流程与要求可通过原文链接查看招标文件。
The SPINTEC laboratory's spin-insulatronics team has issued a call for tender seeking a consultant with expertise in liquid-phase epitaxy (LPE) for crystal growth. This request is part of the four-year MAGISTRAL project, which launched on March 1, 2025, with funding from the French PEPR SPIN exploratory program.
The MAGISTRAL project (MAGnetic dISks as TRansducer of AnguLar momentum) aims to develop novel, ultra-high-fidelity optomechanical modulators operating at GHz frequencies. A core technical requirement is integrating ferrimagnetic materials with exceptionally low magnetic and acoustic losses into optical components. The project team has identified single-crystal yttrium iron garnet (YIG) thin films grown on gadolinium gallium garnet (GGG) substrates via LPE as the material system capable of delivering the world's lowest known losses.
To master this specialized growth technique, the Grenoble-based team requires subcontracting assistance from an expert consultant proficient in LPE, particularly for garnet materials. The consultant's mission will involve supporting the team in developing the necessary thin-film fabrication capabilities.
Interested parties must submit their application via email to Olivier KLEIN at SPINTEC. The deadline for applications is April 30, 2026. Further details on the practical terms of the mission and the full application procedure are available through a dedicated web link provided in the original announcement.
Recruiting consultant in crystal growth by liquid phase epitaxy
Context: In 2025, the spin-insulatronics team of SPINTEC was awarded an exploratory grant from the PEPR SPIN program to develop new types of ultra-high-fidelity optomechanical modulators operating at frequencies in the GHz range and incorporating ferrimagnetic materials into optical components. The project is named MAGISTRAL for MAGnetic dISks as TRansducer of AnguLar momentum. It began on March 1, 2025, and will run for four years.
To achieve our goals, we need to gain access to magnetic thin films with very low magnetic and acoustic losses. The material of choice in this context are single-crystals of yttrium iron garnet (YIG) thin films on gadolinium gallium garnet (GGG) substrates via liquid-phase epitaxy (LPE). These materials currently achieves the lowest known losses.
Position: To assist the Grenoble team in mastering this growth method, we are seeking the assistance of experts in liquid-phase epitaxy (LPE), particularly regarding garnets. This request will take the form of a sub-contracting mission.
For more information on the practical terms, please follow the web link. The document also details the procedures for submitting an application. Applications must be submitted by email to Olivier KLEIN (SPINTEC) by April 30, 2026 (included).
