The Sr3CuPtxxIr1-xO6 system has been considered to be a candidate random quantum spin chain. (RQS). For x=1 adjacent S=1/2 Cu2+ions are antiferromagnetically (AF) coupled to...

We have recently succeeded in measuring the excitation spectrum of charge doped cuprate chains with a 90 degree Cu-O-Cu bonding geometry. This study resolved a long standing...

We wish to measure the magnetic excitations and subgap states in a doped (x=0.06) spin ladder using MERLIN. The purpose of the measurements is to ascertain the relationship...

This proposal is part of our research programme to explore the interplay of thermal and quantum fluctuations near zero-temperature quantum phase transitions. Here we plan to use...

Zeolites are perhaps the most successful microporous materials used for catalysis and separation processes in refineries and chemical industries[1-3]. This is due to the...

Geometric frustration is widely accepted as a paradigm to bring out a novel paramagnetic state. Quasielastic paramagnetic scattering has been studied by neutron scattering so...

We propose to continue our investigation on LET of the Shastry-Sutherland compound SrCu2(BO3)2. The first part of the experiment aims to establish the Q-dependence, which will...

This proposal is part of our research programme to explore the interplay of thermal and quantum fluctuations near zero-temperature quantum phase transitions. Here we apply for a...

beta-Mn metal is a good example of metal close to a magnetic/non-magnetic instability. It doesn't order magnetically at any temperature, and yet has a large Somerfeld constant,...

Hydrogen storage is one of the most important technological issues to be resolved in the move towards a future sustainable hydrogen-based economy. We would like to gain further...

This experiment is part of our research programme to explore novel quantum phases and phase transitions induced by magnetic field in frustrated quantum magnets. The quasi-2D...
