Electrical conduction of Ti/TiOx/Ti structures at low temperatures and high magnetic fields
Marianna Batkovaa, Ivan Batko
We present results of electrical conduction studies of Ti/TiOx/Ti planar structures prepared by tip-induced local anodic oxidation (LAO) of titanium thin films. The prepared struct…
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…
