Emergence of Intergranular Tunneling Dominated Negative Magnetoresistance in Helimagnetic Manganese Phosphide Nanorod Thin Films
B. Muchharla, R. P. Madhogaria, D. DeTellem +8
Helical magnets are emerging as a novel class of materials for spintronics and sensor applications; however, research on their charge and spin transport properties in a thin film f…
Strain-modulated helimagnetism and emergent magnetic phase diagrams in highly crystalline MnP nanorod films
Richa Pokharel Madhogaria, Chang-Ming Hung, Baleeswaraiah Muchharla +7
We explore strain-modulated helimagnetism in highly crystalline MnP nanorod films grown on Si(100) substrates using molecular beam epitaxy. The strained MnP film exhibits a paramag…
Table-like magnetocaloric effect and enhanced refrigerant capacity in EuO1-δ thin films
P. Lampen, R. Madhogaria, N. S. Bingham +6
An approach to adjusting the conduction band population for tuning the magnetic and magnetocaloric response of EuO1-δ thin films through control of oxygen vacancies (δ = 0, 0.025,…
Sub-second and ppm-level Optical Sensing of Hydrogen Using Templated Control of Nano-hydride Geometry and Composition
Hoang Mai Luong, Minh Thien Pham, Tyler Guin +4
The use of hydrogen as a clean and renewable alternative to fossil fuels requires a suite of flammability mitigating technologies, particularly robust sensors for hydrogen leak det…
Evidence of long-range ferromagnetic order and spin frustration effects in the double perovskite
R. P. Madhogaria, R. Das, E. M. Clements +6
We present a comprehensive study on the magnetic structure, dynamics, and phase evolution in the single-phase double perovskite . The mixed valence state due to oxygen…
