Magnetic properties of Mn-doped Bi<sub>2</sub>Te<sub>3</sub> and Sb<sub>2</sub>Te<sub>3</sub>
Choi, Jeongyong,Choi, Sungyoul,Choi, Jiyoun,Park, Yongsup,Park, Hyun-Min,Lee, Hee-Woong,Woo, Byung-Chul,Cho, Sunglae WILEY-VCH Verlag 2004 Physica status solidi. PSS. B, Basic solid state p Vol.241 No.7
<P>We have fabricated Mn-doped Bi<SUB>2</SUB>Te<SUB>3</SUB> and Sb<SUB>2</SUB>Te<SUB>3</SUB> single crystals by the vertical gradient solidification method. The compositions and crystal structures of Bi<SUB>2−x</SUB>Mn<SUB>x</SUB>Te<SUB>3</SUB> and Sb<SUB>2−x</SUB>Mn<SUB>x</SUB>Te<SUB>3</SUB> were determined using Electron Probe Micro-Analyzer (EPMA) and powder X-ray diffraction (XRD) patterns, respectively. Both crystal structures were rhombohedral with smaller lattice constants because of the smaller atomic radius of Mn than those of Bi and Sb. Based on the magnetization measurements, Mn-doped Bi<SUB>2</SUB>Te<SUB>3</SUB> and Sb<SUB>2</SUB>Te<SUB>3</SUB> compounds have ferromagnetic ordering at T<SUB>C</SUB> = 10 and 17 K, respectively.

Field-induced quantum critical point in the pressure-induced superconductor CeRhIn<sub>5</sub>
Park, T.,Tokiwa, Y.,Ronning, F.,Lee, H.,Bauer, E. D.,Movshovich, R.,Thompson, J. D. WILEY-VCH Verlag 2010 Physica Status Solidi. B Vol.247 No.3
<P>When subjected to pressure, the prototypical heavy-fermion antiferromagnet CeRhIn<SUB>5</SUB> becomes superconducting, forming a broad dome of superconductivity (SC) centred around 2.35 GPa (=P2) with maximal T<SUB>c</SUB> of 2.3 K. Above the superconducting dome, the normal state shows strange metallic behaviours, including a divergence in the specific heat and a sub-T-linear electrical resistivity. The discovery of a field-induced magnetic phase that coexists with SC for a range of pressures P ≤ P2 has been interpreted as evidence for a quantum phase transition, which could explain the non-Fermi-liquid behaviour observed in the normal state. Here we report electrical resistivity measurements of CeRhIn<SUB>5</SUB> under magnetic field at P2, where the resistivity is sub-T-linear for temperatures above T<SUB>c</SUB> (or T<SUB>FL</SUB>) and a T<SUP>2</SUP>-coefficient A found below T<SUB>FL</SUB> diverges as H<SUB>c2</SUB> is approached. These results are similar to the field-induced quantum critical compound CeCoIn<SUB>5</SUB> and confirm the presence of a quantum critical point in the pressure-induced superconductor CeRhIn<SUB>5</SUB>.
