Report

Two geometrically frustrated magnets studied by neutron diffraction

Autor: Mirebeau, I., Apetrei, A., Goncharenko, I. N., Moessner, R.

In the pyrochlore compounds, Tb$_2$Ti$_2$O$_7$ and Tb$_2$Sn$_2$O$_7$, only the Tb$^{3+}$ ions are magnetic. They exhibit quite abnormal -- and, in view of their chemical similarity, strikingly different -- magnetic behaviour, as probed by neutron dif

Magnetic structure of CeRhIn_5 as a function of pressure and temperature

Autor: Llobet, A., Gardner, J. S., Moshopoulou, E. G., Mignot, J. -M., Nicklas, M., Bao, W., Moreno, N. O., Pagliuso, P. G., Goncharenko, I. N., Sarrao, J. L., Thompson, J. D.

We report magnetic neutron-diffraction and electrical resistivity studies on single crystals of the heavy-fermion antiferromagnet CeRhIn$_{5}$ at pressures up to 2.3 GPa. These experiments show that the staggered moment of Ce and the incommensurate m

Magnetic fluctuations in frustrated Laves hydrides R(Mn_{1-x}Al_{x})_{2}H_{y}

Autor: Cadavez-Peres, P., Mirebeau, I., Kahn, R., Goncharenko, I. N., Vincent, E., Makarova, O. L.

Publikováno v: Phys. Rev. B 67, 224426 (2003)

By neutron scattering, we have studied the spin correlations and spin fluctuations in frustrated Laves hydrides, where magnetic disorder sets in the topologically frustrated Mn lattice. Below the transition towards short range magnetic order, static

Ferromagnetic Mixed-Valence and Kondo-Lattice State in TmTe at High Pressure

Autor: Link, P., Goncharenko, I. N., Mignot, J. -M., Matsumura, T., Suzuki, T.

Neutron diffraction experiments on TmTe at pressures up to 7 GPa are reported. The semiconductor-to-metal transition occurring at 2 GPa in this compound is accompanied by the appearance of strong ferromagnetic exchange interactions producing a Curie
