Ionic modulation at the LaAlO/KTaO interface for extreme high-mobility two-dimensional electron gas
H. Yan, S. W. Zeng, K. Rubi +5
Due to the coexistence of many emergent phenomena, including 2D superconductivity and a large Rashba spin-orbit coupling, 5d transition metal oxides based two-dimensional electron…
Effect of phonon anharmonicity on ferroelectricity in EuxBa1-xTiO3
Bommareddy Poojitha, Km Rubi, Soumya Sarkar +3
Investigating the competition between ferroelectric ordering and quantum fluctuations is essential to tailor the desired functionalities of mixed ferroelectric and incipient ferroe…
Electrical switching of antiferromagnetic CoO | Pt across the Néel temperature
M. J. Grzybowski, C. F. Schippers, M. E. Bal +5
One of the most important challenges in antiferromagnetic spintronics is the read-out of the Néel vector state. High current densities up to 10 Acm used in the electrica…
Antiferromagnetic Hysteresis above the Spin Flop Field
M. J. Grzybowski, C. F. Schippers, O. Gomonay +11
Magnetocrystalline anisotropy is essential in the physics of antiferromagnets and commonly treated as a constant, not depending on an external magnetic field. However, we demonstra…
Quantum oscillations in an optically-illuminated two-dimensional electron system at the LaAlO/SrTiO interface
I. Leermakers, K. Rubi, M. Yang +9
We have investigated the illumination effect on the magnetotransport properties of a two-dimensional electron system at the LaAlO/SrTiO interface. The illumination signific…
Electronic subbands in the a-LaAlO/KTaO interface revealed by quantum oscillations in high magnetic fields
Km Rubi, Shengwei Zeng, Femke Bangma +4
Investigating Shubnikov-de Haas (SdH) oscillations in high magnetic fields, we experimentally infer the electronic band structure of the quasi-two-dimensional electron gas (2DEG) a…
Large adiabatic temperature and magnetic entropy changes in EuTiO3
A. Midya, P. Mandal, Km Rubi +5
We have investigated the magnetocaloric effect in single and polycrystalline samples of quantum paraelectric EuTiO3 by magnetization and heat capacity measurements. Single crystall…
Giant magnetocaloric effect in magnetoelectric Eu1-xBaxTiO3
Km Rubi, Pawan Kumar, D. V. Maheswar Repaka +3
We report the magnetic entropy change (Delta Sm) in magnetoelectric Eu1-xBaxTiO3 for x = 0.1- 0.9. We find - delta Sm = 11 (40) J/kg.K in x = 0.1 for a field change of 1 (5) Tesla…
