Magnetic excitations in weakly coupled spin dimers and chains material Cu2Fe2Ge4O13

T. Masuda, A. Zheludev, B. Sales +3

Magnetic excitations in a weakly coupled spin dimers and chains compound Cu2Fe2Ge4O13 are measured by inelastic neutron scattering. Both structure factors and dispersion of low ene…

Ordered State in a Haldane Material PbNi $_{2}$ V $_{2}$ O $_{8}$ Doped with Magnetic and Non-Magnetic Impurities

S. Imai, T. Masuda, T. Matsuoka +1

Impurity effect is systematically studied in doped Haldane material Pb(Ni $_{1 - x}$ $M_{x}$ ) $_{2}$ V $_{2}$ O $_{8}$ ( $M$ = Mn, Co, Cu, and Mg) by use of DC and AC susceptibility, and heat capaci…
