Shape memory alloys (SMAs) are a unique class of smart materials exhibiting extraordinary properties with a wide range of applications in engineering, biomedical, and aerospace technologies. In this study, an advanced, efficient, low-cost, and highly scalable laser-assisted imprinting method with low environmental impact to create thermally controllable surface patterns is reported. Two different imprinting methods were carried out mainly on Ni50Ti50 (at. %) SMAs by using a nanosecond pulsed Nd:YAG laser operating at 1064 nm wavelength and 10 Hz frequency. First, laser pulses at selected fluences were directly focused on the NiTi surface, which generated pressure pulses of up to …

Magnetic Anisotropy And Exchange Bias In L10 Fept/Nio Bilayer Thin Films, Zachary B. Leuty
MSU Graduate Theses
Perpendicular exchange bias (PEB), particularly when it persists in nanomaterials to room temperature, is highly useful for applications in spintronic devices and for advancing the development of high-information-density magnetic random access memory. A complete mechanistic and theoretical understanding of exchange bias has evaded scientists. The quest to discover novel materials for magnetic and spintronic device applications has stimulated investigation into nanomaterials having optimal and/or tailored magnetic properties that are based on the exchange bias effect. In this study, pulsed laser deposition was used to grow epitaxial PEB systems of ferromagnetic FePt thin film layers that are interfaced with antiferromagnetic NiO …
