Nonlinear magnetic response in ruthenocuprates

Živković, I.; Awana, V. P.S.; Berger, H. - In: The European Physical Journal B - Condensed Matter and … 62 (2008) 4, pp. 423-431

We have performed an investigation of the nonlinear magnetic response in ruthenocuprates. A negative, diverging-like peak at the main magnetic transition T<Subscript>N</Subscript> in RuSr<Subscript>2</Subscript> RECu<Subscript>2</Subscript>O<Subscript>8</Subscript> (RE=Gd, Y) indicates a possible canted antiferromagnetic order. Another well defined feature above T<Subscript>N</Subscript> points to a blocking...</subscript></subscript></subscript></subscript></subscript>

Softening of spin-wave stiffness near the ferromagnetic phase transition in diluted magnetic semiconductors

Sun, Shih-Jye; Lin, Hsiu-Hau - In: The European Physical Journal B - Condensed Matter and … 49 (2006) 4, pp. 403-406

Employing the self-consistent Green's function approach, we studied the temperature dependence of the spin-wave stiffness in diluted magnetic semiconductors. Note that the Green's function approach includes the spatial and temperature fluctuations simultaneously which was not possible within...

Weak ferromagnetism in LaMnO<Subscript>3</Subscript>

Skumryev, V.; Ott, F.; Coey, J.; Anane, A.; Renard, J.; … - In: The European Physical Journal B - Condensed Matter and … 11 (1999) 3, pp. 401-406

The magnetic properties of (La<Subscript>1 − x </Subscript>Sr<Subscript> x </Subscript>)MnO<Subscript>3</Subscript> crystals have been studied. The ac susceptibility χ=χ′ + iχ″ has been measured at frequencies ranging from 10 Hz to 1 000 Hz. The x=0.25 crystal shows a typical ferromagnetic behaviour with a dimensionless SI susceptibility of 6 below T...</subscript></subscript></subscript></subscript>
