Anisotropic Electronic Structure of the Two-Dimensional Electron Gas at the AlOx/KTaO3(110) interface
E. A. Martínez, J. Dai, M. Tallarida +2
Oxide-based two-dimensional electron gases (2DEGs) have generated significant interest due to their potential for discovering novel physical properties. Among these, 2DEGs formed i…
Depth Profile of the Phase Transition of the FeRh Alloy in FeRh/BaTiO3
Attila Lengyel, Gábor Bazsó, Aleksandr I. Chumakov +9
We report on the depth dependence and technological limits of the phase transition of the iron rhodium alloy as function of temperature, external magnetic and electric fields in th…
Ultralong spin lifetime in light alkali atom doped graphene
B. G. Márkus}, P. Szirmai, K. F. Edelthalhammer +9
Today's great challenges of energy and informational technologies are addressed with a singular compound, the Li and Na doped few layer graphene. All what is impossible for graphit…
Low thermal conductivity in La-filled cobalt antimonide skutterudites with an inhomogeneous filling factor prepared under high-pressure conditions
F. Serrano-Sánchez, J. Prado-Gonjal, N. M. Nemes +7
La-filled skutterudites LaxCo4Sb12 (x : 0.25 and 0.5) have been synthesized and sintered in one step under high-pressure conditions at 3.5 GPa in a piston-cylinder hydrostatic pres…
Low temperature magnetic transitions of single crystal HoBi
A. Fente, H. Suderow, S. Vieira +4
We present resistivity, specific heat and magnetization measurements in high quality single crystals of HoBi, with a residual resistivity ratio of 126. We find, from the temperatur…
Room Temperature In-plane <100> Magnetic Easy Axis for Fe3O4/SrTiO3(001):Nb Grown by Infrared PLD
Matteo Monti, Mikel Sanz, Mohamed Oujja +15
We examine the magnetic easy-axis directions of stoichiometric magnetite films grown on SrTiO3:Nb by infrared pulsed-laser deposition. Spin-polarized low-energy electron microscopy…
Testing the Elliott-Yafet spin-relaxation mechanism in KC8; a model system of biased graphene
Gábor Fábián, Balázs Dóra, Ágnes Antal +6
Temperature dependent electron spin resonance (ESR) measurements are reported on stage 1 potassium doped graphite, a model system of biased graphene. The ESR linewidth is nearly is…
Density of states deduced from ESR measurements on low-dimensional nanostructures; benchmarks to identify the ESR signals of graphene and SWCNTs
Péter Szirmai, Gábor Fábián, Balázs Dóra +6
Electron spin resonance (ESR) spectroscopy is an important tool to characterize the ground state of conduction electrons and to measure their spin-relaxation times. Observing ESR o…
Phase segregation on the nanoscale in Na2C60
G. Klupp, P. Matus, D. Quintavalle +6
Na2C60 is believed to be an electron-hole counterpart of the Mott-Jahn--Teller insulator A4C60 salts. We present a study of infrared, ESR, NMR spectroscopy, X-ray diffraction, chem…
Static and dynamic Jahn-Teller effect in the alkali metal fulleride salts A4C60 (A = K, Rb, Cs)
G. Klupp, K. Kamaras, N. M. Nemes +2
We report the temperature dependent mid- and near-infrared spectra of K4C60, Rb4C60 and Cs4C60. The splitting of the vibrational and electronic transitions indicates a molecular sy…
Ordered low-temperature structure in K4C60 detected by infrared spectroscopy
K. Kamaras, G. Klupp, D. B. Tanner +3
Infrared spectra of a K4C60 single-phase thin film have been measured between room temperature and 20 K. At low temperatures, the two high-frequency T1u modes appear as triplets, i…
