Critical Scaling of the Magnetization and Magnetostriction in the Weak Itinerant Ferromagnet UIr (2008)

Knafo, W., Meingast, C., Sakarya, S., Van Dijk, N. H., Huang, Y., Rakoto, H., ...

The weak itinerant ferromagnet UIr is studied by magnetization and magnetostriction measurements. Critical behavior, which surprisingly extends up to several Tesla, is observed at the Curie...

Heat Capacity and Magnetic Phase Diagram of the Low-Dimensional Antiferromagnet Y$_2$BaCuO$_5$ (2008)

Knafo, W., Meingast, C., Inaba, A., Wolf, Th., Löhneysen, H. V.

A study by specific heat of a polycrystalline sample of the low-dimensional magnetic system Y$_2$BaCuO$_5$ is presented. Magnetic fields up to 14 T are applied and permit to extract the ($T$,$H$)...

Importance of In-Plane Anisotropy in the Quasi Two-Dimensional Antiferromagnet BaNi$_{2}$V$_{2}$O$_{8}$ (2006)

Knafo, W., Meingast, C., Grube, K., Drobnik, S., Popovich, P., Schweiss, P., ...

The phase diagram of the quasi two-dimensional antiferromagnet BaNi$_{2}$V$_{2}$O$_{8}$ is studied by specific heat, thermal expansion, magnetostriction, and magnetization for magnetic fields applied...

Further analysis of the quantum critical point of Ce$_{1-x}$La$_{x}$Ru$_{2}$Si$_{2}$ (2006)

Raymond, S., Knafo, W., Flouquet, J., Lejay, P.

New data on the spin dynamics and the magnetic order of Ce$_{1-x}$La$_{x}$Ru$_{2}$Si$_{2}$ are presented. The importance of the Kondo effect at the quantum critical point of this system is emphasized...

Thermal expansion of the quasi two-dimensional magnetic layered compound BaNi$_{2}$V$_{2}$O$_{8}$ under magnetic fields along c-axis (2006)

Knafo, W., Meingast, C., Grube, K., Drobnik, S., Popovich, P., Schweiss, P., ...

The quasi two-dimensional magnetic BaNi$_{2}$V$_{2}$O$_{8}$ is studied by using high-resolution thermal expansion in magnetic fields up to 10 T applied along the c-axis. A slight increase of about 1...

Superconductivity mediated by a soft phonon mode: specific heat, resistivity, thermal expansion and magnetization of YB6 (2005)

Lortz, R., Wang, Y., Tutsch, U., Abe, S., Meingast, C., Popovich, P., ...

The superconductor YB6 has the second highest critical temperature Tc among the boride family MBn. We report measurements of the specific heat, resistivity, magnetic susceptibility and thermal...

Artificial scaling laws of the dynamical magnetic susceptibility in heavy-fermion systems (2005)

Knafo, W., Raymond, S.

We report here how artificial, thus erroneous, scaling laws of the dynamical magnetic susceptibility can be obtained when data are not treated carefully. We consider the example of the heavy-fermion...

Low energy spin fluctuations in the heavy fermion compound Ce$_{0.925}$La$_{0.075}$Ru$_{2}$Si$_{2}$ (2005)

Knafo, W., Raymond, S., Fåk, B., Adams, M. A., Lejay, P., Flouquet, J.

We report inelastic neutron scattering measurements performed on a single crystal of the heavy fermion compound Ce$_{0.925}$La$_{0.075}$Ru$_{2}$Si$_{2}$, which is at the borderline between an...

Anomalous scaling behavior of the dynamical spin susceptibility of Ce$_{0.925}$La$_{0.075}$Ru$_{2}$Si$_{2}$ (2004)

Knafo, W., Raymond, S., Flouquet, J., Fåk, B., Adams, M. A., Haen, P., ...
