Vortex confinement through an unquantized magnetic flux
Geunyong Kim, Jinyoung Yun, Jinho Yang +7
Geometrically confined superconductors often experience a breakdown in the quantization of magnetic flux owing to the incomplete screening of the supercurrent against the field pen…
Local characterization of a heavy-fermion superconductor via sub-Kelvin magnetic force microscopy
Dirk Wulferding, Geunyong Kim, Hoon Kim +5
Using magnetic force microscopy operating at sub-Kelvin temperatures we characterize the heavy-fermion superconductor CeCoIn. We pinpoint the absolute London penetration depth…
Direct observation of the M2 phase with its Mott transition in a VO film
Hoon Kim, Tetiana V. Slusar, Dirk Wulferding +7
In VO, the explicit origin of the insulator-to-metal transition is still disputable between Peierls and Mott insulators. Along with the controversy, its second monoclinic (M2)…
Construction of a He magnetic force microscope with a vector magnet
Jinho Yang, Ilkyu Yang, Yun Won Kim +5
We constructed a He magnetic force microscope operating at the base temperature of 300 mK under a vector magnetic field of 2-2-9 T in the direction. Fiber optic interfe…
Spatially resolved penetration depth measurements and vortex manipulation in the ferromagnetic superconductor ErNi2B2C
Dirk Wulferding, Ilkyu Yang, Jinho Yang +6
We present a local probe study of the magnetic superconductor, ErNiBC, using magnetic force microscopy at sub-Kelvin temperatures. ErNiBC is an ideal system to expl…
Magnetic domain tuning and the emergence of bubble domains in the bilayer manganite LaSrMnO (x=0.32)
Juyoung Jeong, Ilkyu Yang, Jinho Yang +11
We report a magnetic force microscopy study of the magnetic domain evolution in the layered manganite LaSrMnO (with ). This strongly correlated el…
Ferroelectric and Magnetic Domains in LuFe2O4 Observed by Scanning Probe Microscopy
I. K. Yang, J. Kim, S. H. Lee +3
LuFe2O4 is a multiferroic system which exhibits ferroelectricity, charge order, and ferrimagnetic order simultaneously below ~230 K. The ferroelectric domains of LuFe2O4 are imaged…
