“…Above 1 T it decreases about linearly, with a slope dR/dH ≈ −0.2% per Tesla. A similar behavior was also observed for Ru-1212 and Ru-2212 polycrystalline samples [88,68], where the negative magnetoresistance was attributed to interactions between the charge carriers (flowing in-plane through either the CuO2 or the RuO2 planes) and the localized Ru spins becoming more ordered in external fields. As we will see below at least the interlayer supercurrents are of the tunneling type.…”

“…Zero resistance is reached at Tc = 16 K. The Curie temperature of this sample is about 133 K. Note that near this temperature the resistance vs. temperature curve exhibits a small cusp. The transition to the superconducting state has been investigated with various methods, including measurements of specific heat [18,68] ensuring that the superconductivity observed is indeed a bulk effect coexisting with ferromagnetism. Similar to the cuprates also in the the ruthenocuprates the hole doping of the CuO2 layers can be altered by substituting proper elements.…”

The recently discovered ruthenocuprates have attracted great interest because of the microscopic coexistence of superconducting and ferromagnetic order. Typically, these materials become magnetically ordered at temperatures around 125-145 K and superconductivity sets in between 15 and 50 K. While superconductivity arises in the CuO2 layers the RuO2 layers in between order magnetically. In this paper we summarize some of the crystallographic, magnetic and superconducting properties of the ruthenocuprates, as obtained from investigations on polycrystalline samples as well as single crystals. RésuméDécouverts récemment, les ruthenocuprates ont suscité un intérêténormeà cause de la coexistence d'un ordre supraconducteur et ferromagnétique. Dans ces matériaux, la phase magnétique apparaît autour de 125-145 K et la phase supraconductrice entre 15 et 50 K. Les couches de CuO2 sont supraconductrices et ce sont les couches interstitielles de RuO2 qui sont ordonnées magnétiquement. Dans cet article nous résumons quelques-unes des propriétés cristallographiques, magnétiques et supraductrices des ruthenocuprates déduites desétudes sur deś echantillons polycristallins ainsi que sur des monocristaux.
