Intrinsic vs. Extrinsic Magnetic Transitions in Sr3Ru2O7 films
R. Choudhary, A. Rajapitamahuni, S. Guo +4
In scientific research, both positive and negative results play crucial role in advancing the field. Negative results provide valuable insights that can guide future experiments an…
Thickness-dependent insulator-to-metal transition in epitaxial RuO2 films
Anil Kumar Rajapitamahuni, Sreejith Nair, Zhifei Yang +4
Epitaxially grown RuO2 films on TiO2 (110) exhibit significant in-plane strain anisotropy, with a compressive strain of - 4.7% along the [001] crystalline direction and a tensile s…
Hysteretic Magnetoresistance in a Non-Magnetic SrSnO3 Film via Thermal Coupling to Dynamic Substrate Behavior
Laxman Raju Thoutam, Tristan K. Truttmann, Anil Kumar Rajapitamahuni +1
Hysteretic magnetoresistance (MR) is often used as a signature of ferromagnetism in conducting oxide thin films and heterostructures. Here, magnetotransport is investigated in a no…
Solid Source Metal-Organic Molecular Beam Epitaxy of Epitaxial RuO2
William Nunn, Sreejith Nair, Hwanhui Yun +5
A seemingly simple oxide with a rutile structure, RuO2 has been shown to possess several intriguing properties ranging from strain-stabilized superconductivity to a strong catalyti…
Impurity Band Conduction in Si-doped \b{eta}-Ga2O3 Films
Anil Kumar Rajapitamahuni, Laxman Raju Thoutam, Praneeth Ranga +2
By combining temperature-dependent resistivity and Hall effect measurements, we investigate donor state energy in Si-doped \b{eta}-Ga2O3 films grown using metal-organic vapor phase…
