Effect of Co doping and hydrostatic pressure on SrFe2As2
E. Lengyel, M. Kumar, W. Schnelle +2
We report a pressure study on electron doped SrFeCoAs by electrical-resistivity () and magnetic-susceptibility () experiments. Application of either external…
Avoided ferromagnetic quantum critical point in CeRuPO
E. Lengyel, M. E. Macovei, A. Jesche +3
CeRuPO is a rare example of a ferromagnetic (FM) Kondo-lattice system. External pressure suppresses the ordering temperature to zero at about GPa. Our ac-susceptibili…
Temperature - pressure phase diagram of CeCoSi: Pressure induced high-temperature phase
E. Lengyel, M. Nicklas, N. Caroca-Canales +1
We have studied the temperature-pressure phase diagram of CeCoSi by electrical-resistivity experiments under pressure. Our measurements revealed a very unusual phase diagram. While…
Hydrostatic and chemical pressure tuning of CeFeAs_1-xP_xO single crystals
K. Mydeen, E. Lengyel, A. Jesche +2
We carried out a combined P-substitution and hydrostatic pressure study on CeFeAs_1-xP_xO single crystals in order to investigate the peculiar relationship of the local moment magn…
Pressure Tuning of the Interplay of Magnetism and Superconductivity in CeCu2Si2
E. Lengyel, M. Nicklas, H. S. Jeevan +2
We carried out specific-heat and ac-susceptibility experiments under hydrostatic pressure to investigate the interplay of spin-density-wave antiferromagnetism (A) and superconducti…
Competition of local-moment ferromagnetism and superconductivity in Co-substituted EuFe2As2
M. Nicklas, M. Kumar, E. Lengyel +2
In contrast to SrFe2As2, where only the iron possesses a magnetic moment, in EuFe2As2 an additional large, local magnetic moment is carried by Eu2+. Like SrFe2As2, EuFe2As2 exhibit…
Temperature - pressure phase diagram of the superconducting iron pnictide LiFeP
K. Mydeen, E. Lengyel, Z. Deng +3
Electrical-resistivity and magnetic-susceptibility measurements under hydrostatic pressure up to p = 2.75 GPa have been performed on superconducting LiFeP. A broad superconducting…
Pressure-induced change of the pairing symmetry in superconducting CeCu2Si2
E. Lengyel, M. Nicklas, H. S. Jeevan +5
Low-temperature (T) heat-capacity measurements under hydrostatic pressure of up to p=2.1 GPa have been performed on single-crystalline CeCu2Si2. A broad superconducting (SC) region…
Magnetism and unconventional superconductivity in CeMIn heavy-fermion crystals
J. D. Thompson, M. Nicklas, A. Bianchi +15
We review magnetic, superconducting and non-Fermi-liquid properties of the structurally layered heavy-fermion compounds CeMIn (M=Co, Rh, Ir). These properties sug…
Response of the Heavy-Fermion Superconductor CeCoIn to Pressure: Roles of Dimensionality and Proximity to a Quantum-Critical Point
M. Nicklas, R. Borth, E. Lengyel +6
We report measurements of the pressure-dependent superconducting transition temperature and electrical resistivity of the heavy-fermion compound CeCoIn. Pressure moves Ce…
