9317338 Vittoria Technical abstract: Standard lithographic techniques will be used to construct a planar microwave device which will be capable of measuring microwave resonance signals over a probe area of 0.1 x 0.1 micron2 of a magnetic thin film. Current operational devices probe areas of 100 x 100 micron2. Measurements of the microwave resonance spectra as a function of probe size will be performed on standard metal films. It is expected that these devices will be useful for the study of magnetic thin films and multilayers, fine powders, and single magnetic domains. Non-technical abstract: Many interesting magnetic phenomena occur on a very small (less than 1/1000 of a millimeter) scale. These are often related to structurally small objects such as fine powders but also include microscopic magnetic phenomena. Standard magnetic characterization techniques can determine only an average property. It is proposed to build and test a device which will be capable of performing magnetic measurements on a scale of 1/1000mm. The device will be useful for studying a variety of thin films as well as magnetic powders. ***

9317338 Vittoria 技术摘要：标准光刻技术将用于构建平面微波装置，该装置能够在磁性薄膜的 0.1 x 0.1 微米的探针区域上测量微波谐振信号。 当前运行的设备探测面积为 100 x 100 微米2。 将在标准金属薄膜上进行作为探针尺寸函数的微波共振光谱的测量。 预计这些设备将可用于磁性薄膜和多层、细粉末和单磁畴的研究。 非技术摘要：许多有趣的磁现象发生在非常小的（小于 1/1000 毫米）尺度上。 这些通常与细粉末等结构较小的物体有关，但也包括微观磁性现象。 标准磁性表征技术只能确定平均特性。 建议建造并测试一种能够在 1/1000mm 范围内进行磁性测量的装置。 该设备可用于研究各种薄膜和磁粉。 ***
