Here, we report a study on the anisotropic metamagnetic (MM) behavior of Ca 2− x Sr x RuO 4 (for x =0.2) by electrical transport and magnetization measurements at high magnetic fields ( B ). With increasing field as the MM transition is crossed and

Since the discovery of superconductivity, there has been a drive to understand the mechanisms by which it occurs. The BCS (Bardeen-Cooper-Schrieffer) model successfully treats the electrons in conventional superconductors as pairs coupled by phonons

Local magnetic measurements utilizing a micro-Hall probe were performed on a superconducting heavy fermion CeCoIn5 single crystal. We show that the critical current follows a power law as predicted by Ginzburg–Landau theory. This behavior is found

To understand the electronic structure of the heavy fermion superconductors CeMIn 5, we have performed a comprehensive magnetic study of these materials.1-4 Our quantum oscillation studies reveal that the Fermi surface becomes systematically more 2-d

The novel coordination polymer [Co4(2,2′-bipy)4(H2O)2(btec)2]n (btec = 1,2,4,5-benzenetetracarboxylate), 1, has been hydrothermally synthesized. X-Ray diffraction experiments reveal that 1 exhibits an interesting two-dimensional (2D) chiral undulat

The de Haas\char21{}van Alphen (dHvA) effect is used to study angular-dependent extremal areas of the Fermi surfaces and effective masses of ${\mathrm{Ce}}_{x}{\mathrm{La}}_{1\ensuremath{-}x}{\mathrm{B}}_{6}$ alloys for x between 0 and 0.05. The dHvA

We investigate the magnetic field dependence of the spin-Peierls transition in ${\mathrm{NaV}}_{2}{\mathrm{O}}_{5}$ in the field range 16--30 T. The transition temperature exhibits a very weak variation with the field, suggesting an unusual mechanism

Scaling of low-temperature magnetization data for the non-Fermi-liquid systems ${\mathrm{UCu}}_{4}\mathrm{Pd}$ and ${\mathrm{UCu}}_{3.5}{\mathrm{Pd}}_{1.5}$ in fields to 30 T is carried out to help determine the nature of the magnetic interactions ab
