Giant magneto-optical response in non-magnetic semiconductor BiTeI driven by bulk Rashba spin splitting
L. Demkó, G. A. H. Schober, V. Kocsis +7
We study the magneto-optical (MO) response of polar semiconductor BiTeI with giant bulk Rashba spin splitting at various carrier densities. Despite being non-magnetic, the material…
Disorder promotes ferromagnetism: Rounding of the quantum phase transition in Sr_{1-x}Ca_xRuO_3
L. Demko, S. Bordacs, T. Vojta +8
The subtle interplay of randomness and quantum fluctuations at low temperatures gives rise to a plethora of unconventional phenomena in systems ranging from quantum magnets and cor…
Multicritical end-point of the first-order ferromagnetic transition in colossal magnetoresistive manganites
L. Demkó, I. Kézsmárki, G. Mihály +3
We have studied the bandwidth-temperature-magnetic field phase diagram of RE(0.55)Sr(0.45)MnO(3) colossal magnetoresistance manganites with ferromagnetic metallic (FM) ground state…
Magnetic-field-induced transition in BaVS3
P. Fazekas, N. Barisic, I. Kezsmarki +4
The metal-insulator transition (MIT) of BaVS3 is suppressed under pressure and above the critical pressure of p~2GPa the metallic phase is stabilized. We present the results of det…
