Effect of pressure on electric transport properties of carbon-doped EuB6
M. Batkova, I. Batko, E. Bauer +3
We report about influence of external pressure on electrical resistivity of EuB5.99C0.01, the compound believed to be intrinsically inhomogeneous due to fluctuation of carbon conte…
Electrical properties of SmB thin films prepared by pulsed laser deposition from a stoichiometric SmB target
Marianna Batkova, Ivan Batko, Feliks Stobiecki +4
Possible existence of topologically protected surface in samarium hexaboride has created a strong need for investigations allowing to distinguish between properties coming from the…
Evidence formagnetic phase separation in colossal magnetoresistance compound EuB5.99C0.01
Ivan Batko, Marianna Batkova, Vinh Hung Tran +2
EuB5.99C0.01 is a low-carrier density ferromagnet that is believed to be intrinsically inhomogeneous due to fluctuations of carbon content. In accordance with our previous studies,…
SmB6: A material with anomalous energy distribution function of charge carriers?
I. Batko, M. Batkova
We argue that because of valence-fluctuation caused dynamical changes (fluctuations) of impurity energies in an impurity band of valence fluctuating semiconductors both occupied an…
Low temperature resistivity studies of SmB6: Observation of twodimensional variable-range hopping conductivity
Marianna Batkova, Ivan Batko, Slavomir Gabani +3
We studied electrical resistance of a single-crystalline SmB6 sample with a focus on the region of the "low-temperature resistivity plateau". Our observations did not show any true…
Calorimetric tunneling study of heat generation in metal-vacuum-metal tunnel junction
I. Batko, M. Batkova
We have proposed novel calorimetric tunneling (CT) experiment allowing exact determination of heat generation (or heat sinking) in individual tunnel junction (TJ) electrodes which…
