Intrinsic tunneling in phase separated manganites.
We present evidence of direct electron tunneling across intrinsic insulating regions in submicrometer wide bridges of the phase-separated ferromagnet (La,Pr,Ca)MnO3. Upon cooling below the Curie temperature, a predominantly ferromagnetic supercooled state persists where tunneling across the intrinsic tunnel barriers (ITBs) results in metastable, temperature-independent, high-resistance plateaus...

متن کاملIntensity studies of inelastic electron tunneling spectra
Inelastic electron tunneling spectroscopy (IETS) using metal}insulator}metal (MIM) tunnel junctions is an established technique for studying the vibrational modes of molecules adsorbed on metal surfaces. We are examining a new geometry for IETS in which the oxide layer of the MIM junction is replaced by an atomically thin gas "lm. `Cleana junctions in which the barrier is composed of pure neon ...
متن کاملTunneling spectra for (dx2−y2 + is)-wave superconductors versus tunneling spectra for (dx2−y2 + idxy)-wave superconductors
The tunneling conductance spectra of a normal metal / insulator / singlet superconductor is calculated from the reflection amplitudes using the BlonderTinkham-Klapwijk (BTK) formulation. The pairing symmetry of the superconductor is assumed to be dx2−y2 + is, or dx2−y2 + idxy. It is found that in the (dx2−y2 + is)-wave case there is a well defined conductance peak in the conductance spectra, in...
