The Crossover Between Giant Magnetoresistance and Superconductivity in RuSr2G...
Giant magnetoresistance (GMR) is observed up to -49% in RuSr2R1.8-xY0.2CexCu2O10-d ruthenocuprates. The magnetotransport is very sensitive to lattice effects. As , the mean A... -
A New Metamagnetic Material CoSr2Nd1.1Ce0.9CuO9±d
A new metamagnetic material CoSr2Nd1.1Ce0.9CuO9±d has been synthesised. At 2 K the metamagnetic transition occurs at a field of 0.1 T. We propose to measure the field dependence... -
A Neutron Diffraction study of the novel layered cuprate IrSr2154Sm1.15Ce0.85...
We have synthesised a novel material IrSr2Sm1.15Ce0.85Cu2O10 . Preliminary magnetic measurements evidence two magnetic transitions at Tc = 125 K and TM2= 6 K. Above Tc however... -
Colossal Magnetoresistance in PrBa2Cu3O7-d
Large negative bulk magnetoresistance has recently been observed in ruthenocuprate materials RuSr2R2-xCexCu2O10-d (up to -47 % at 5 K in a 9 T field). This material exhibits -MR... -
A muSR spectroscopic study of the spin dynamics and reentrant spin-glass tran...
We have recently synthesised the novel iridocuprate IrSr2Sm1.15Ce0.85Cu2O10. This material exhibits a complex temperature dependence of the magnetic susceptibility with multiple... -
Is Ba2PrMoO6 a valence bond glass? A MuSR spectroscopic study
It has recently been proposed that Ba2YMoO6 is the first example of an exotic valence bond glass (VBG), which is characterized by an amorphous arrangement of spin dimers and...
