The knowledge of the properties of the grains and their grain boundaries is essential for the further optimization of sample performance of various high-T c samples (YBa2Cu3O y (YBCO), Bi-based cuprates, MgB2, iron-based materials). In these material

We have successfully fabricated La1-x Sr x MnO3 (LSMO) nanowires with various x level, and La1.85Sr0.15CuO4 (LSCO) nanowires/nanoribbons via electrospinning. The colossal magnetoresistance (CMR) of the LSMO nanowire networks have been investigated. a

To optimize the performance of the high-frequency magnetic force microscopy (HFMFM) technique, we investigate the effect of varying the frequency of the amplitude modulation on the magnetic contrast achieved. As samples, we employ hard disk writer po

AFM and STM scans on SmBa2Cu3Ox (SmBCO) melt processed samples revealed nanoscale stripe-like structures, sometimes parallel over several micrometers, sometimes wavy. These structures consist of chemical compositional fluctuations and act as effectiv

The time dependence of flux patterns obtained on an untwinned Y Ba2Cu3O7−δ single crystal showing the 'meandering instability' is observed at T = 65 K using magneto-optical imaging. When applying a reversed external field to a remanent state, alon

The scaling of the normalized volume pinning forces, Fp/Fp,max, versus a reduced field h=Ha/Hscale has proven to be a very informative tool to study the origin of the flux pinning in superconductors. Remarkably, on Bi2Sr2Ca2Cu3O10+δ (Bi-2223) and Bi
