Systematic Control of Strain-Induced Perpendicular Magnetic Anisotropy in Epitaxial Europium and Terbium Iron Garnets Thin Films
Victor H. Ortiz, Mohammed Aldosary, Junxue Li +6
We show tunable strain-induced perpendicular magnetic anisotropy (PMA) over a wide range of thicknesses in epitaxial ferrimagnetic insulator Eu3Fe5O12 (EuIG) and Tb3Fe5O12 (TbIG) t…
Synthesis, processing and transport properties of cubic and trigonal solid solutions in the Mg-Si-Sn system
Pathikumar Sellappan, Anthony Y. Fong, Masayuki Murata +2
Mg-Si-Sn solid solutions have interesting and useful semiconducting properties particularly for thermoelectric applications. While cubic solid solutions have been prepared by a var…
Anomalous Hall hysteresis in Tm3Fe5O12/Pt with strain-induced perpendicular magnetic anisotropy
Chi Tang, Pathikumar Sellappan, Yawen Liu +3
We demonstrate robust interface strain-induced perpendicular magnetic anisotropy in atomically flat ferrimagnetic insulator Tm3Fe5O12 films grown with pulsed laser deposition on su…
Predicting Failure: Acoustic Emission of Berlinite under Compression
Guillaume F Nataf, Pedro O Castillo-Villa, Pathikumar Sellappan +4
Acoustic emission has been measured and statistical characteristics have been analyzed during the stress-induced collapse of porous berlinite, AlPO4, containing up to 50 vol% poros…
Acoustically Transparent Alumina-based Cranial Implants Enhance Ultrasound Transmission Through a Combined Mechano-Acoustic Resonant Effect
Mario Ibrahin Gutierrez, Pathikumar Sellappan, Elias H. Penilla +4
Therapeutic ultrasound for brain stimulation has increased in the last years. This energy has shown promising results for treating Alzheimers disease, Parkinsons disease, and traum…
An integrated approach to doped thin films with strain tunable magnetic anisotropy: Powder synthesis, target preparation and pulsed laser deposition of Bi:YIG
Pathikumar Sellappan, Chi Tang, Jing Shi +1
We present a synthesis/processing method for fabricating ferrimagnetic insulator (Bi-doped yttrium iron garnet) thin films with tunable magnetic anisotropy. Since the desired magne…
