Angle resolved NMR in more and less unusual magnets

Nuclear magnetic resonance (NMR) relaxation (1/T_1) is a very powerful 
experimental technique to understand magnetic materials, particularly when 
the normal, dipolar magnetic order has melted away, such as often occurs due 
to frustration. However, the interpretation of the experiments remains 
tricky. We develop the theory of NMR relaxation first in collinear magnets, 
such as the Fe-pnictides and the cuprates, and then in various frustrated 
systems. In particular we would like to propose an experiment that could 
recognise a spin nematic state, which is the quantum analogue of a liquid 
crystal.
