Modeling, Fabrication, and Characterization of Magnetic Thin Films for Integrated Inductor and MRAM Applications

Creator:

Buford, Benjamin

Abstract:

Magnetic thin films have potential to improve devices such as on-chip inductors, and enable new technologies such as magnetic random access memory (MRAM). The use of magnetic cores in on-chip inductors is typically limited to applications well under 1 GHz. At higher frequencies, the performance of the magnetic core is...

A technique for error estimation of linewidth and damping parameters extracted from ferromagnetic resonance measurements

Creator:

Buford, Benjamin, Dhagat, Pallavi, and Jander, Albrecht

Abstract:

Ferromagnetic resonance (FMR) characterization, using a vector network analyzer (VNA), is widely used to determine anisotropy, g-factor, and Gilbert damping parameter of magnetic thin films, but results are typically reported without calculation of the measurement accuracy. We present a method of processing VNA-FMR measurements to determine both the value and...

Writing magnetic patterns with surface acoustic waves

Creator:

Li, Weiyang, Buford, Benjamin, Jander, Albrecht, and Dhagat, Pallavi

Abstract:

A novel patterning technique that creates magnetization patterns in a continuous magnetostrictive film with surface acoustic waves is demonstrated. Patterns of 10 μm wide stripes of alternating magnetization and a 3 μm dot of reversed magnetization are written using standing and focusing acoustic waves, respectively. The magnetization pattern is size-tunable,...

Measuring the inverse magnetostrictive effect in a thin film using a modified vibrating sample magnetometer

Creator:

Buford, Benjamin, Dhagat, Pallavi, and Jander, Albrecht

Abstract:

A method for measuring the magnetostriction of thin films using a vibrating sample magnetometer is described. We describe the design of a custom sample holder to apply an adjustable bending stress to the sample during measurement and observe the resulting change in the M-H loop.
