Influence of carbon-ion irradiation on the superconducting critical properties of MgB thin films
Soon-Gil Jung, Seung-Ku Son, Duong Pham +4
We investigate the influence of carbon-ion irradiation on the superconducting critical properties of MgB thin films. MgB films of two thicknesses viz. 400 nm (MB400nm) and…
Enhanced magnetic and thermoelectric properties in epitaxial polycrystalline SrRuO3 thin film
Sungmin Woo, Sang A Lee, Hyeona Mun +11
Transition metal oxide thin films show versatile electrical, magnetic, and thermal properties which can be tailored by deliberately introducing macroscopic grain boundaries via pol…
Tuning electromagnetic properties of SrRuO3 epitaxial thin films via atomic control of cation vacancies
Sang A Lee, Seokjae Oh, Jegon Lee +9
Elemental defects in transition metal oxides is an important and intriguing subject that result in modifications in variety of physical properties including atomic and electronic s…
Revisiting optical properties of MgB with a high-quality sample prepared by a HPCVD method
Yu-Seong Seo, Jae Hak Lee, Won Nam Kang +1
We investigated a high-quality MgB thin film with a thickness of 1000 nm on an AlO substrate using optical spectroscopy. We measured the reflectance spectra…
Beyond Bean's critical state model: On the origin of paramagnetic Meissner effect
Sangjun Oh, Dong Keun Oh, Won Nam Kang +4
Solving phenomenological macroscopic equations instead of microscopic Ginzburg-Landau equations for superconductors is much easier and can be advantageous in a variety of applicati…
Anomalous scaling behavior in a mixed-state Hall effect of a cobalt-doped BaFe2As2 epitaxial film with a high critical current density over 1 MA/cm2
Hikaru Sato, Takayoshi Katase, Won Nam Kang +3
The mixed-state Hall effect was examined in a Ba(Fe1-xCox)2As2 epitaxial film with a high critical current density. The transverse resistivity ρxy and the longitudinal resistivity…
