The oscillations in the longitudinal magnetoresistance of alpha-(BEDT-TTF)(2)KHg(SCN)(4) are shown to be strongly attenuated with decreasing temperature if the sample is in a state where it displays the quantum Hall effect. We provide evidence that t

We report measurements of the longitudinal magnetoresistance and magnetization of in pulsed magnetic fields of up to 50 T and temperatures down to 400 mK, using samples of different purity. Below 2 K the amplitude of the Shubnikov - de Haas oscillati

The Fermi surface of CeB 6 is found to be very similar to that of PrB 6 , with an electron pocket of almost the same size as that in PrB 6 . We have confirmed a discrepancy between the cyclotron mass determined by the de Haas-Van Alphen effect and th

Departures from standard Lifshitz-Kosevich behavior observed in the oscillatory magnetization and magnetoresistance of bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) charge-transfer salts in high magnetic fields are investigated using a numerical m

With the aid of numerical modelling and recent pulsed magnetic field experiments, we discuss the applicability of the established magnetic breakdown and quantum interference theories to κ-(BEDT-TTF)2Cu(NCS)2. We pay particular attention to the possi

A new type of dilution refrigerator is described with easy loading of the sample directly into the dilute phase in the mixing chamber. Electrical, optical and mechanical services to the sample are readily incorporated and electrically insulating tail

The de Haas-van Alphen effect has been studied in CeAl2 at temperatures down to 17mK. Some features of the results are found to bear a strong resemblance to those in LaAl2 suggesting that the f-electrons in CeAl2 are well localized and, whilst strong

New dHvA effect results are presented for three cerium based Kondo lattice compounds, CeCu6, CeAl2 and CeB6. Such experiments confirm rather directly the existence of quasiparticles with strongly enhanced masses. A comparison with band structure calc

We report on measurements of the de Haas-van Alphen effect in the heavy electron metal CeCu6 in the coherent state. At least eight dHvA frequencies are observed with cyclotron masses as large as 80m0. Compared with LaCu6 the measured masses are great
