Mentor: Dr. Mark Meisel
College of Liberal Arts and Sciences
"The Scholars program has shown itself to be an excellent way to network with other like minded undergraduate students. I hope to become a better researcher and presenter through all of the workshops the program has to offer. My goals for the academic year are to finish strong in my remaining upper division classes while concluding my research in Dr. Meisel's lab."

Construction and Operation of a Differential Hall Element Magnetometer
My research project is to construct and implement a novel magnetometer that will characterize magnetic materials at room temperature. Currently, many labs utilize a SQUID (Superconducting Quantum Interference Device) magnetometer. However, long user queues can develop and create extensive wait times for SQUID use due to the high demand for characterization of new samples from various collaborations. With a new magnetometer, many of these samples can be run at room temperature, allowing more efficient sample characterization and increasing interdisciplinary collaboration. The new magnetometer, referred to as the Differential Hall Element Magnetometer, or more simply as the DHEM, utilizes the Hall effect to identify key magnetic features of a sample, such as the coercive field and magnetic saturation. The DHEM consists of two matched Hall elements that are swept through the bore of a room temperature 9 Tesla superconducting magnet via a linear stepper motor. The sample is located on top of one element while the other is blank, thereby serving as the control element. Each Hall element is biased with a constant current and outputs a voltage that is proportional to the external magnetic field. The difference between these two voltages is then taken via a differential op amp circuit. This differential voltage can then be converted to the magnetization of the sample by multiplication of a constant. Current research includes the complete automation of the DHEM system using a LabVIEW program. In addition, the system itself can be simplified by the fabrication of a constant low-current power supply that will be precise and accurate enough to output 35 mA over all field strengths. Finally, the system will be tested for a new figure of merit. These findings will be presented at the 2013 APS March Meeting.
